2023 Cactus & Succulent Update Part 1

Agave (Syn. xMangave) ‘Pineapple Express’ at 10″ tall x 18″ wide on 10-23-23.

Hello everyone! I hope tis post finds you well. The temps have been great and we are getting some rain. We have made it through most of October without a dreaded “F”, but this weekend will be very cold. Since it would be raining all week, I decided to bring the plants on the back porch inside on the 23rd before they got wet. As usual, most of them will get measured and photographed. I started with the back porch on Monday the 23rd then moved to the front porch and worked until it was too dark to take photos then finished on the 24th.

In all, despite the heat and drought, the plants on the back porch did quite well. I kept the cactus and succulents on the front porch last summer, but I put the plants on this post on the back porch for 2023. There were no issues with sunburn or anything else.

As usual, you can click on the plant’s name to go to their own pages.

The Agave ‘Pineapple Express’, top photo, has been on the back porch this summer for a change. It changed colors in the sun, but it did very well and has grown to 10″ tall x 18″ wide. It is online as xMangave ‘Pineapple Express’, but as previously mentioned, xMangave is a synonym of Agave. I am curious, though, since Manfredia is now a synonym of Agave, does the patented name xMangave ‘Pineapple Express’ actually become Agave ‘Pineapple Express’? Hmmm…

Callisia repens (Bolivian Jew) on 10-23-23, #967-3.

Of course, the Callisia repens (Bolivian Jew) isn’t a cactus or succulent, but it is a neat plant and it likes the full sun on the back porch. I have grown these for a few years and they grow and grow until I bring them inside for the winter. They usually fizzle out after that… Their stems take root in every pot around them and would probably be best suited in a hanging pot. Maybe next year…

<<<<+>>>>

Cereus repandus f. monstruosus ‘Rojo’ at 10 3/4″ tall x 4 1/2″ wide on 10-23-23.

The Cereus repandus f. monstruosus ‘Rojo’ had made it through its sixth summer and is now 10 3/4″ tall x 4 1/2″ wide (at its widest part). It is a “monstrose” form of the Peruvian Apple Cactus… It is a really neat cactus and one I should buy more of. No two monstrose forms are alike.

<<<<+>>>>

Delosperma echinatum (Pickle Plant) on 10-23-23, #967-7.

I have grown a Delosperma echinatum (Pickle Plant) for a few years but I haven’t had a good one… I must admit, this one has done much better despite its pot being invaded by its neighbor Callisia repens… The pot is half and half. I brought the pot inside and put it on the kitchen windowsill. We’ll see which one dies first. I haven’t been able to overwinter a Pickle Plant either… No page for this one.

<<<<+>>>>

Dracaena hanningtonii ’Samurai’/‘Dwarf Samurai’ at 4 1/2″ tall x 6 1/2″ wide, the offset 4 1/2″ tall x 4 5/8″ wide on 10-23-23, #967-8.

Hmmm… This Dracaena hanningtonii ‘Samurai’/’Dwarf Samurai’ has grown to 4 1/2″ tall x 6 1/4″ wide. I noticed when I put the plants outside in May it was sprouting a kid… Now, I brought this plant home in January 2020 when it was 3″ tall and it has grown 3/4″ every year. This kid comes along and grows to 4 1/2″ tall x 4 5/8″ wide in just a few months!!! Actually, I fudged a little because the parent is actually only 4 1/4″ tall, but I couldn’t let the kid get the advantage…

If you look for one of these neat plants, it may be labeled as Sansevieria hanningtonii with a cultivar name of ‘Samurai’ or ‘Dwarf Samurai’…

<<<<+>>>>

Ferocactus wislizeni (Fishhook Barrel Cactus) at 3 3/4″ tall x 3″ wide on 10-23-23, #967-15.

I have been wondering about the Ferocactus wislizeni (Fishhook Barrel Cactus) for a while… At one point I thought it was dying, but it always looks a bit pale toward the bottom. It has grown 5/8″ since last October to 3 3/4″ tall x 3″ wide. GOOD JOB Wisley!

<<<<+>>>>

Gymnocalycium saglionis (Giant Chin Cactus) at 2 5/8″ tall x 3 1/2″ wide on 10-23-23, #967-18.

The Gymnocalycium saglionis (Giant Chin Cactus) has been a great plant since I bought home in 2019. It just takes its time watching everything going on around it without complaint. It has made it to 2 5/8″ tall, but shrunk a little around the waist to 3 1/2″. Normally, this guy has no complaints, but I promised him a new pot… Well, it fell apart while I was moving the plant to the table to take his photo. He just looked at me with a “?”…

<<<<+>>>>

Kroenleinia grusonii (Golden Barrel Cactus), both at 4″ tall x 3 1/2″ wide on 10-23-23, #967-20.

Greater and Lessor Kroenleinia grusonii (Golden Barrel Cactus) have finally caught up with each other at 4″ tall x 3 1/2″ wide. Last year Lessor was a little bigger than Greater… You know they always try to fool me, but this time they were calm. Hmmm…

<<<<+>>>>

Mammillaria hahniana (Old Lady Cactus) at 5 3/4″ tall x 3 3/4″ wide on 10-23-23, #967-22.

Mammillaria hahniana (Old Lady Cactus) is looking great as always and has grown to 5 3/4″ tall x 3 3/4″ wide. It had a growth spurt last year while on the front porch growing 1 3/4″ in one year to 5 1/2″. I measured it again a month later and it shrunk to 4 3/4″. That’s normal since it didn’t have any water. You know, they swell up with water… 🙂 I really like this cactus and it is one of several of the older ones I have had since 2016.

<<<<+>>>>

Mammillaria karwinskiana (Silver Arrows) at 5″ tall x 3 1/2″ wide on 10-23-23, #967-24.

The Mammillaria karwinskiana (Silver Arrows) is another great wooly Mammillaria that is easy to grow. It has reached 5″ tall x 3 1/2″ wide and was a mere 1 7/8″ tall x 2 3/16″ wide when I brought it home in 2018.

<<<<+>>>>

Mammillaria muehlenpfordtii (Golden Pincushion) at 5 1/2″ tall x 3 1/2″ wide on 10-23-23, #967-26.

The Mammillaria muehlenpfordtii (Golden Pincushion) is another great Mammillaria I brought home in 2018. I remember it lying on its side out of its pot on the clearance rack. It smiled so I brought it home. Its blue-green color, long golden spines, and club-shaped growth habit make it a great addition to the collection. It is now 5 1/2″ tall x 3 1/2″ wide and hasn’t done much leaning this past year. This is one of a few species that divide dichotomously, meaning it will divide. It may grow offsets, but that hasn’t happened yet either… Believe it or not, a piece of the hot glue used to attach a strawflower to this plant is STILL lower down on the plant…

<<<<+>>>>

Mammillaria mystax at 3 1/2″ tall x 3 1/4″ wide on 10-23-23, #967-28.

Mammillaria mystax is a great companion that always looks great. It has been carefree and dark green since I brought it home in 2018. It was only 1 3/4″ tall then and has grown to 3 1/2″ tall x 3 1/4″ wide.

<<<<+>>>>

Mammillaria plumosa (Feather Cactus) at 2 1/2″ tall x 4 3/4″ wide on 10-23-23, #967-30.

The Mammillaria plumosa (Feather Cactus) has been a charmer for sure. I bought it from a seller on Ebay in 2019 and it came wrapped in toilet paper at only 3/4″ tall with a few offsets that measured a total of 2 1/4″ wide. The tallest in the center is now 2 1/2″ wide and the clump measures 4 3/4″ wide. It may look soft and cuddly, but it does have short spines…

<<<<+>>>>

Parodia magnifica (Ball Cactus/Balloon Cactus) at 3″ tall x 3″ wide on 10-23-23, #967-32.

The Parodia magnifica (Ball Cactus/Balloon Cactus) is always neat with deep ribs, soft golden spines, and an odd hairdo. It was only 1 3/8″ tall x x 2 3/8″ wide when I brought it home in 2019 and is now 3″ tall x 3″ wide.

<<<<+>>>>

Peperomia ferreyrae at 6 1/2″ tall x 7 1/2″ wide on 10-23-23, #967-34.

I finally found another Peperomia ferreyrae at Wagler’s Greenhouse in May, so I had to bring it home. I brought my first one when I was living at the Mansion in Mississippi in 2012 and brought it with me when I moved back here in 2013. I don’t want to talk about what happened to it and most of my other plants, but it won’t happen again… It had nothing to do with my parents. Anyway, this plant has grown well over the summer and now measures 6 1/2″ tall x 7 1/2″ wide.

<<<<+>>>>

Stenocereus pruinosus (Gray Ghost/Organ Pipe) at 7 1/4″ tall x 3 1/4″ wide on 10-23-23, #967-36.

What would life be without the Stenocereus pruinosus (Gray Ghost)? One of the oldest in my cactus collection, now measuring 7 1/4″ tall x 3 1/4″ wide. I brought it home in 2016 when it was 2 7/8″ tall x 2 3/4″ wide. I like the way the pattern of gray bloom spreads out over the stem. It does need repotting like the rest of the cactus do… The coloration at the bottom is normal.

I lost a few last winter due to a mealybug issue still lingering from the plants that were shipped to me a few years ago. Sadly, the pair of Parodia lenninghausii and Echinopsis ‘Rainbow Bursts’ were among them, just as the Mammillaria pringlei and Mammillaria rhodantha were the year before. There have been a few more than that, but I really don’t want to talk about it.

There are a few more plants on the back porch I forgot to take until the 24th that will be on the next post, or maybe the next…

Until next time, be safe, stay positive, and always be thankful!

Cactus & Succulent Update 2022

Cereus repandus f. montruosus ‘Rojo’ on 10-16-22, #919-6.

Hello everyone! I hope this post finds you well. The dreaded time of the year has arrived and I had to move the potted plants inside on January 16. I was still working on one last new wildflower ID and still needed a few leaf and stem photos. I had already taken photos, but the leaf and stem photos were blurry. I’m not sure if I can still take any since the “F”, and since then the wind has been blowing. Of course, it warmed back up…

As always, I take photos and measure the cactus and some of the succulents as I bring them back inside. Most of the plants were on the front porch this summer because the heat and the intense sun seemed a little too much for some of them last summer. Yeah, I know they are cacti, but that doesn’t necessarily mean they like intense sun. Many smaller species grow in the shade of taller plants.

Last winter was not too good… My son and his friend were still here so they used the back bedroom. I usually kept the back bedroom cooler with a plant shelf in the south-facing window for the succulents and part of the cacti. but the shelf was placed in front of the east-facing sliding door in the dining room. Instead of the cactus being on a table in front of the sliding door, they were on another shelf in my bedroom. I couldn’t very well keep the temperature cooler in either place. They are gone now, thank goodness, so the plants are basically where they should be.

As a result of more heat, for one thing, I lost a few plants over last winter from mealybugs… GEEZ! I think the worst was losing both Mammillaria pringlei and rhodantha… I also lost the Aloe ‘Lizard Lips’. I had all three of those for MANY YEARS.

Anyway, here we go in alphabetical order… You can click on the plant’s name under the photo to go to their own pages.

<<<<Aloe ‘Cha Cha’>>>>

Aloe ‘Cha Cha’ on 10-16-22, #919-1.

Aloe ‘Cha Cha’ is the last survivor of the five plants I received from Succulent Market in 2020. Ummm… I am trying not to mention… No, I’m not going to do it! I did mention A. ‘Lizard Lips’ contacted mealybugs, but not from A. ‘Cha Cha’. Somehow it never had them and has done weirdly well… Of course, as you may be able to tell, it is a miniature.

<<<<Aloe maculata>>>>

Aloe maculata on 10-16-22, #919-2.

Hmmm… I just discovered a problem with starting at the beginning of the alphabet. Maybe I should have started at the end. Although the Aloe maculata are all doing GREAT as always, I have been promising it I would divide their pot for a couple of years. Maybe three. I had one in another pot that “somehow” contacted mealy bugs last winter and they kept coming back. So, I did a terrible thing and threw it out the back door. The big pot was in my bedroom and it would get an occasional bug but nothing serious. Isolating this plant would be a problem, so I decided to put it in the basement in front of a window. I remember I kept a lot of plants in the basement during the winter before and they always did fine. Well, the bugs didn’t like the conditions and they left and the Aloe came through with flying colors like it had been in perfect conditions. These plants are descendants of the Aloe maculata I called ‘Kyle’s Grandma’ that was given to me by a good friend, Kyle, when I was living in Mississippi. The plant, actually I think there were two, were from his grandma, Brenda, in 2009.

I was just thinking maybe I should use the basement as a quarantine station. 🙂 Well, if the plants are halfway dormant…

<<<<Austrocylindropuntia subulata (Eve’s Needle)>>>>

Austrocylindropuntia subulata (Eve’s Needle) at 7″ tall on 10-16-22, #919-3.

Another hmmm… As I looked at this plant, it started tapping its feet. It asked, “Do you notice something?” I said, “Ummm…” Last fall I told this Austrocylindropuntia subulata that I would move it back to the center of the pot in the spring. As you can see, it is still not in the center. Maybe, in the back of my mind, I was thinking it would move by itself. I know the original plant was in the center when I brought it home from Wagler’s Greenhouse in 2019 when it was just a single stub at only 4 1/2″ tall. Now, it has grown appendages and its offset is 7″ tall…

<<<<Cereus repandus f. montruosus ‘Rojo’>>>>

Cereus repandus f. montruosus ‘Rojo’ at 10″ tall x 4 1/4″ wide on 10-16-22, #919-5.

At least the Cereus repandus f. montruosus ‘Rojo’ didn’t give me any dirty looks and seemed to be quite content on the front porch. It grew another 1/4″ and is now 10″ tall. The top photo is the upper portion of this plant. I brought this plant home in 2018 when it was only 5 1/2″ tall. I really like monstrous forms of cacti.

<<<<Crassula ovata ‘Gollum’>>>>

Crassula ovata ‘Gollum’ at 10 1/2 tall x 10″ wide on 10-16-22, #919-7.

The Crassula ovata ‘Gollum’ did very well in its usual spot over the summer on the front porch. I brought this plant home in 2018 when it was 7″ tall and it is now 10 1/2″ tall. I always like the tree-like appearance of older Crassula ovata. I had a fairly large Crassula ovata and a nice C. ovata ‘Lady Fingers’ that were AWESOME!

Crassula ovata ‘Gollum’ on 10-16-22, #919-8.

They can attract brown scale (from somewhere) which are easily removed with your fingernail. If you don’t keep an eye on them, the scale can spread to all the leaves and become a pain… Especially when you have a bigger plant with A LOT of leaves

<<<<Echinopsis ‘Rainbow Bursts’>>>>

Echinopsis ‘Rainbow Bursts’ at 4 1/4″ tall x 7 1/4″ wide on 10-16-22, #919-9.

The Echinopsis ‘Rainbow Bursts”…GEEZ! I lost my train of thought. I have thought about removing her kids, but then I think about what she would look like all naked. No doubt, her trunk would be all brown and terribly unsightly so I just keep the family together. Someday, I hope to see flowers. After all, I have had this pot since 2016 and who knows how old it was before I brought it home. The main plant was only 2 1/4″ tall x 3 1/2″ wide when I brought it home, and the offsets were growing along its ribs. Now it is 4 1/4″ tall and the whole cluster is 7 1/4″ wide. This plant was originally x Echinobivia ‘Rainbow Bursts’ and was described as an intergeneric cross between Echinopsis and Lobivia. Lobivia is now a synonym of Echinopsis, so I guess it wasn’t an intergeneric cross after all. 🙂 It was named “Rainbow Bursts” because of their “spectacular colors” (so the label said) over the spring and summer. STILL WAITING…

I was watching a YouTube video from Morris Park in the Ozarks a couple of pots that looked similar. With all the offsets and everything.

I still have the big pot of Echinopsis huascha, but they are looking very weird…

<<<<Espostoa melanostele subsp. nana>>>>

Espostoa melanostele subsp. nana (Peruvian Old Lady)at 9″ tall on 10-16-22, #919-10.

The Espostoa melanostele subsp. nana (Peruvian Old Lady) always seems happy no matter where she is sitting. She may have been happier on the front porch out of the wind so her hair doesn’t get messed up. She has grown another 1/2″ over the summer to 9″ tall. Hard to imagine she was only 2 3/4″ tall when I brought her home in 2016.

<<<<Euphorbia trigona ‘Rubra’>>>>

Euphorbia trigona ‘Rubra’ (African Milk Tree) at 19 1/2″ tall on 10-16-22, #919-11.

To say this Euphorbia trigona ‘Rubra’ has grown would be an understatement. I brought it home from Mast’s Greenhouse in June of 2021 when it was 6 1/4″ tall. By the time I moved the plants inside in October, it had grown to 10 3/4″. Every time I looked at the plants over the summer, I noticed this plant was growing and even had an offset. Well, lately, I had been busy and hadn’t paid much attention to the plants on the front porch. So, when I started moving the plants inside in 2022 I was SHOCKED! This plant had grown to 19 1/2″ tall!

Euphorbia trigona ‘Rubra’ on 10-16-22, #919-12.

Euphorbia trigona was named and described as such by Philip Miller in the eighth edition of The Gardener’s Dictionary in 1768. I don’t know where he found it exactly, but it wasn’t in the wild… You see, there are no known plants of this species in the wild, and it is possibly of hybrid origin. Information also says this species does not produce flowers. Hmmm… As with all Euphorbia, it does produce a milky latex sap.

<<<<Ferocactus wislizeni>>>>

Ferocactus wislizeni (Fishhook Barrel Cactus) at 3 1/8″ tall x 3″ wide on 10-16-22, #919-13.

The Ferocactus wislizeni (Fishhook Barrel Cactus) has done quite well on the front porch and has now reached 3 1/8″ tall. This guy always got a little sunburned on the back porch, but it has had no problems on the front porch. It was only 1 5/8″ tall when I brought it home in 2019, so it has done well.

<<<<x Gasteraloe ‘Flow’>>>

x Gasteraloe ‘Flow’ at 4″ tall x 4″ wide on 10-16-22, #919-14.

I had to throw out my older x Gasteraloe ‘Flow’ in January because of mealybugs. I had sprayed, washed them off, etc. and I finally had to give up. Repeatedly working the plant over seemed to make the plant suffer more (especially during its rest period). I was happy to find a new one at the Kuntry Store in July that was 3″ tall x 3 3/4″ wide. There were some really nice larger plants in combination planters, but I only wanted ‘Flow’. GEEZ, I hate it when that happens. It has grown to 4″ tall x 4″ wide since I brought it home. The plant didn’t have any sort of label, but I am assuming it is x Gasteraloe ‘Flow’.

<<<<Gasteria ‘Little Warty’>>>>

Gasteria ‘Little Warty’ at 6 7/8″ tall x 7 1/8″ wide on 10-16-22, #919-16.

The Gasteria ‘Little Warty’ continued to do well and is now 6 7/8″ tall x 7 1/8″ wide. I really like this little guy. It was only 2″ tall x 2 13/16″ wide when I brought it home in 2019. The mealy bugs tried to infect this plant but had no luck.

<<<<Gasteria sp. ?>>>>

Gasteria sp. at 5 1/4″ tall x 7 1/8″ wide on 10-19-22, #919-16.

I thought I was going to lose this Gasteria last winter because of its issues with mealybugs. It still isn’t quite back to normal but it is OK. It even grew to 5 1/4″ tall x 7 1/8″ wide. I think I may put it in the cool front bedroom with plants that aren’t bothered by critters and keep an eye on it. Maybe I should put it in the basement… I would hate to lose it after almost 5 years. I was kind of surprised it had mealy bug issues since its leaves are so hard, but they attacked way down where the leaves attach. A very hard spot to get to.

<<<<Gymnocalycium saglionis>>>>

Gymnocalycium saglionis (Giant Chin Cactus) at 2 3/4″ tall x 3 3/4″ wide on 10-16-22, #919-17.

The Gymnocalycium saglionis (Giant Chin Cactus) had never had one single issue. No rust spots, sunburn, bugs, or anything. It has grown from 1 1/8″ tall x 2 5/8″ wide in 2019 to 2 3/4″ tall x 3 3/4″ wide. It had its biggest growth spurt in the first 7 months after I brought it home, and since then it has just grown slow and steady. At least it is still alive and well.

<<<<Haworthiopsis limifolia>>>>

Haworthiopsis limifolia (File-Leaved Haworthia) at 5 1/8″ tall x 6″ wide on 10-16-22, #919-18.

Formerly Haworthia limifolia, the Haworthiopsis limifolia continues to do remarkably well without a hitch. These plants are normally sold under the name Haworthia limifolia ‘Fairy Washboard’, but that is actually a common name along with File-Leaved Haworthia, Fairies Washboard, Swaiti Haworthia, and possibly others. The last name is possibly what it is called in Southeast Africa where the species grows in the wild. There are five varieties of the species… This plant has now grown to 5 1/8″ tall x 6″ wide from 2 3/8″ tall x 3″ wide when I brought it home in May of 2019. Who wouldn’t like its dark green color with all those ridges on the leaves?

<<<<Kalanchoe daigremontiana>>>>

Kalanchoe daigremontiana (Alligator Plant) at 27 3/4″ tall x 7 1/2″ wide on 10-16-22, #919-19.

I finally found a nice Kalanchoe daigremontiana (Alligator Plant). You may remember the “other” Kalanchoe daigremontiana (Mother Of Thousands) I have… I always thought something was a little whacky with the name, and then I finally figured out it was a Kalanchoe laetivirens. Anyway, when I was plant shopping at Wagler’s Greenhouse this summer, I saw they had quite a few of real Kalanchoe daigremontiana. Of course, I had to bring one home… It was 13 1/4″ tall x 13 1/2″ wide when I brought it home in May and now it is a shocking 27 3/4″ tall. Some of the lower leaves have fallen off, so the width has shrunk to 7 1/2″ wide.

Normally, I would have repotted this plant, but since I was a bad parent in 2022 it is STILL in its 4 1/2″ pot I brought it home in. GEEZ! Luckily, it performs a balancing act quite well. It was between two bricks on the plant table, which most of the plants were (or tucked in pot-to-pot) so the wind would blow them around. Right now, it is standing next to the kitchen sink. I am trying to figure out where to put it for the winter…

Kalanchoe daigremontiana (Alligator Plant) on 10-16-22, #919-20.

Like the Kalanchoe laetivirens (or x laetivirens since it is a cross between two species), this one also gives birth to plantlets along its leaves (which aren’t really leaves). I removed them before I brought it into the house. I learned a lesson from before…

Kalanchoe daigremontiana (Alligator Plant) on 10-16-22, #919-21.

This species has the purplish marking on its, umm… You know what I mean. A spider decided this plant’s “leaves” made a good home and it was COVERED in webs. I should have taken a photo, but that would have proved my neglect… I guess I could have said it was decorated for Halloween. 🙂 I don’t have a page for this plant yet.

<<<<Kalanchoe thyrsiflora>>>>

Kalanchoe thyrsiflora (Paddle Plant) at 14 1/4 ” tall on 10-16-22, #919-22.

I found several awesome Kalanchoe thyrsiflora (Paddle Plant) at Mast’s Greenhouse in May and thought I needed to bring one home. I was surprised with buds when I was bringing the plants inside since they weren’t there the week before (unless I wasn’t paying attention). It was 6″ tall x 7 3/4″ wide when I brought it home, and now it is 14 1/4″ tall including the buds. Won’t this be interesting? Ummm… I have no page for this plant yet either.

The Kalanchoe beharensis ‘Fang’, K. laetivirens, all the K. luciae, and K.orgyalis (Copper Spoons) are still alive but need some work… Sadly, the K. gastonis-bonnieri (Donky Ears) and K. beharensis didn’t survive last winter. The K. marmorata (Penwiper Plant) also finally gave it up. We had our ups and downs since 2018.

<<<<Kroenleinia grusonii>>>>

Kroenleinia grusonii (Golden Barrel Cactus)… Greater (green pot) at 3 1/2″ tall x 3 1/4″ wide, and Lessor (orange pot) at 3 3/4″ tall x 3 1/4″ wide on 10-16-22, #919-23.

These two comedians of the group are still alive and well. The Kroenleinia grusonii (Golden Barrel Cactus) both continue growing head to head. I named them Greater and Lessor in 2016 because the one in the green pot has always been a little taller than the other. Lessor, in the orange or red pot (I can’t decide what color it is), has always been a little shorter and wider. Well, this year they are both 3 1/4″ wide, but Lessor is 1/4″ taller than Greater. Of course, they tried their best to convince me they traded pots. Crazy guys! Measuring them is tricky enough with them jiggling around and standing on their toes.

Apparently, the orange spots on these two guys was rust. Rust can be treated if you know what it is in the first place. Well, the rust issue has gone away, and the orange spots have turned white. Now that I know what it was, I will keep an eye on them.

<<<<Mammillaria hahniana>>>>

Mammillaria hahniana (Old Lady Cactus) at 5 1/2″ tall x 3 3/8″ wide on 10-16-22, #919-24.

This Mammillaria hahniana (Old Lady Cactus) is now the oldest Mammillaria in my collection since M. pringlei and M. rhodantha died. This awesome cactus has now grown to 5 1/2″ tall x 3 3/8″ wide from 1 7/8″ tall x 2 3/8″ wide in 2016. It has been a great cactus and is a free bloomer when it gets in the mood. Old Woman Cactus is the common name iNaturalist gives this species…

<<<<Mammillaria karwinskiana>>>>

Mammillaria karwinskiana (Silver Arrows) at 4 1/2″ tall x 3 1/2″ wide on 10-16-22, #919-25.

When I was measuring Mammillaria karwinskiana (Silver Arrows) it told me it had an itch and asked me to give it a scratch. I was kind of speechless. It has barely ever spoken to me and now it wants a scratch. GEEZ! It just as well ask for a massage. Anyway… This cactus has done very well and has grown another 1/2″ taller and is about the same width as last year. It now stands at 4 1/2″ tall and is 3 1/2″ wide. To think it was just 1 7/8″ tall x 2 3/16″ when I brought it home in 2019. I really like its wool, hairiness, and those long, straight, white spines. But a scratch is out of the question.

<<<<Mammillaria muehlenpfordtii>>>>

Mammillaria muehlenpfordtii (Golden Pincushion) at 5 1/4″ tall x 3″ wide on 10-16-22, #919-26.

The Mammillaria muehlenpfordtii (Golden Pincushion) has been a great plant since I brought it home from Lowe’s in September in 2019. Its pot was lying on the plant shelf with the plant not even in the pot. I am sure it appreciates being brought home. I have always admired its blue-green color and all those golden spines, but the long central spines and short radial spines are also neat. It has grown to 5 1/4″ tall x 3″ wide and was 3 1/4″ tall x 2 1/8″ wide when I brought it home.

<<<<Mammillaria mystax>>>>

Mammillaria mystax at 2 3/4″ tall x 3 1/8″ wide on 10-16-22, #919-27.

Very funny… The Mammillaria mystax shrunk! The measurement from last year was 3 1/4″ tall x 3 1/4″ wide and now it is 2 3/4″ tall x 3 1/8″ wide. Heck, it was 2 3/4″ tall in 2020. It has grown quite a bit, though, since it was just 1 3/4″ tall x 2 1/4″ wide when I brought it home in 2018. Sometimes that happens with cacti when they don’t have enough water. That is likely the case since they were under the roof of the front porch and most of the time just received rain as it blew in on them. I am not complaining that it shrunk especially since it is partly my fault. OK, it was likely all my fault. But, it was safe from the scorching sun on the front porch which I know it appreciated. How do I know? Well, it was smiling at me when I measured it and took its photo.

<<<<Mammillaria plumosa>>>>

Mammillaria plumosa (Feather Cactus) at 2″ tall x 4 1/4″ wide on 10-16-22, #919-28.

It is certainly a good thing this Mammillaria plumosa (Feather Cactus) hasn’t had any problems with mealybugs. How would you tell? I bought this cactus from a seller on Ebay in 2018 and it has been great. In fact, it is the only cactus I bought from Ebay that has survived. Even though it was very small at 3/4″ tall x 2 1/4″ wide it has done very well. The main plant has grown to 2″ tall and the whole cluster is now 4 1/2″ wide. This one you can pet if you so desire…

I lost several Mammillaria since last winter including M. decipiens (Bird’s Nest Cactus) that did very well since 2018, M. elongata (Lady Finger Cactus) that I brought home in 2018, M. pringlei and M. rhodantha I already mentioned, M. senilis (the one with the hooked spines I could never tell if it was alive or dead) since 2020, both M. vetula including ‘Arizona Snowcap’, and M. compressa from 2020. The M. spinosissima ‘Un Pico’ is still alive but looks terrible with A LOT of rust or something… One of the plants in the pot of 3 already died… I have learned that even though many species of Mammillaria are some of the best cacti to grow, when you bring home very small plants you are taking a risk. Also, many species on the market haven’t been in cultivation that long and may not be good choices. Big growers plant seeds by the thousands and don’t necessarily care if they are good choices for pot culture. These days some companies aren’t even putting the names on the pots because they have no clue.

<<<<Opuntia monacantha var. variegata>>>>

Opuntia monacantha var. variegata (Joseph’s Coat) at 12 3/8″ tall x 4 1/2″ wide on 10-16-22, #919-29.

You know, I really haven’t been into variegated cacti, but this Opuntia monacantha var. variegata (Joseph’s Coat) I saw at Wagler’s Greenhouse in 2020 caught my eye. It was only 4 3/4″ tall when I brought it home, and it has grown to 12 3/8″. It is very interesting…

Opuntia monacantha var. variegata (Joseph’s Coat) on 10-16-22, #919-30.

Actually, Llifle (Encyclopedia of Living Forms) has it listed as Opuntia monacantha f. monstruosa variegata (syn. Opuntia monacantha var. variegata cv. Maverick variegata). Which is a synonym of Opuntia monacantha… You know, someone always has to give it a cultivar name when it isn’t necessarily a cultivar. It is one of very few naturally occurring variegated cacti and it is a monstrose form. It is a dwarf, teratological variant of the larger Opuntia monacantha. Anyway, something weird is going on with its main stem… What are those protruberances? Could they be buds? I checked out photos on iNaturalist for the species and that could be very possible… Time will tell and keep your fingers crossed they don’t fall off if they are buds. You never know since I moved it into the house in a different light.

<<<<Parodia lenninghausii>>>>

Parodia lenninghausii, the orange pot on the right is 6 1/2″ tall x 2 3/4″ wide, and the green pot on the left is 7″ tall x 2 1/8″ wide on 10-16-22, #919-31.

The two Parodia lenninghausii (Golden Ball or Lemon Ball Cactus) are more serious than the two Kroenleinia grusonii, but they do have their moments. Sometimes these two agree with each other, and at other times they seem to have had a disagreement and won’t even look at each other. I kind of screwed up and named them Greater and Lessor as well, so I may have to change that. They have also done the switch… Lessor, in the green pot, is now taller than Greater… Lessor is now 7″ tall x 2 1/8″ wide, and Greater is 6 1/2″ tall x 2 1/8″ wide. Hmmm… I have been enjoying these two since 2-1-16. That was when I bought several cacti from Walmart and didn’t notice I bought two Parodia lenninghausii and two Kroenleinia grusonii until I was home… I am glad I brought two of each home to compare with each other as they grow.

<<<<Parodia magnifica>>>>

Parodia magnifica (Ball or Balloon Cactus) at 2 7/8″ tall x 3 1/8″ wide on 10-16-22, #919-32.

The Parodia magnifica (Ball or Balloon Cactus) has done very well and has grown to 2 7/8″ tall but has shrunk 1/8″ to 3 1/8″ wide. It has a few brown spots that I am not sure what the cause is. I was watching a video on YouTube from Morris Park in the Ozarks where he talked about several issues with his cactus. This could be scarring from getting cold or perhaps from stretching as it grows… Apparently, it isn’t hurting it since it is growing and seems healthy otherwise. The marks are smooth without any sign of any kind of infection, past or present.

Parodia magnifica from the top on 10-16-22, #919-33.

I really like the top view with its wool along the tips of the ridges and golden spines.

<<<<Polaskia chichipe>>>>

Polaskia chichipe (Chichipe), the taller plant on the right was 3 7/8″ tall x 1 1/2″ wide, and the one on the right was 3 1/4″ tall x 2 5/8″ wide on 10-16-22, #919-34.

The Polaskia chichipe (Chichipe, ETC.) has done pretty well considering they don’t look that great. I’m not sure what happened to the one on the left, but the one on the right had straw flower damage. You know, those silly fake flowers they stick on with some kind of glue. Perhaps the other marks are naturally occurring as the plants grow. The big scar on the one on the right is likely from the straw flower. There were three plants in the pot, but one died last winter. The plant on the right now measures 3 7/8″ tall x 1 1/2″ wide, while the one on the left is 3 1/4″ tall x 2 5/8″ wide.

<<<<Stenocereus pruinosus>>>>

Stenocereus pruinosus (Gray Ghost, ETC.) at 6 1/4″ tall x 3 1/8″ wide on 10-16-22, #919-35.

The Stenocereus pruinosus (Gray Ghost, Organ Pipe, ETC.) is still alive and well. This has been a great cactus. It now measures 6 1/4″ tall x 3 1/8″ wide from 2 7/8″ tall x 2 3/4″ wide when I brought it home in 2016. I always liked the V-shaped pattern on its trunk. This seems to be an easy-to-grow species, so if you find one…

<<<<Tephrocactus articulatus var. papyracanthus>>>>

Tephrocactus articulatus var. papyracanthus (Paper Spine Cactus) on 10-16-22, #919-36.

The Tephrocactus articulatus var. papyracanthus is always the last on the list but is usually one of the first to be photographed. This Paper Spine Cactus caught my eye when I was plant shopping at Walmart on February 9 in 2016 because of its unusual spines. I was about to put it in my cart when I found a segment lying on the shelf. I decided to take the segment and put the pot back on the shelf. It has been very interesting to watch grow to say the least.

Tephrocactus articulatus var. papyracanthus (Paper Spine Cactus) on 919-37.

In the wild, their segments fall off and take root wherever they land. If an animal passes by, they also hitch a ride on its fur and do a little traveling. When I notice a segment has fallen off I just face it upward in the pot and it takes root. It has done well for the last couple of years and none of the segments have fallen off. The tallest has made it to 4″ tall without falling apart. The pot is getting crowded, so I should give it more space. Ummm… It has been in this pot since 2018. I did put a segment that had fallen off into another pot and it is doing well. I may give it to Mrs. Wagler of Wagler’s Greenhouse since we share plants. I haven’t seen any of these for sale at Wal-Mart or Lowe’s since 2016, so I am very glad I brought the stub home.

Overwintering “desert” cactus isn’t that hard as long as you don’t water them. If you do, just a little no more than once a month )or so) is sufficient. Tropical cacti, like Christmas Cactus and Epiphyllum, need a comfortable temperature and pretty much regular watering. I still have the three Epiphyllum that Tony Tomeo sent and they are doing well. They are quite interesting and somewhat entertaining. One was on the front porch and two on the back porch over the summer with the Stapelia gigantea. The Schlumbergera have had their ups and downs over the summer because they didn’t get enough water (bad parenting). One has buds already and it was outside!

Anyway, there are many websites online about overwintering cacti inside. Reading one is sufficient because if you read several you might be confused. The care they suggest is somewhat controversial especially as far as the temperature. Once temps outside cools off and the day length decreases, they go into dormancy mode. I always put them somewhere the temperature will be about the same when I bring them in. You don’t really want to bring them in from 40° F outside temp to 70° inside. Typically, I water them pretty well a week or so before I bring them inside so I won’t have to water them for a while. Well, I didn’t do that this time because I simply screwed up then evening temps started getting too cool. The debate right now is do I put the cactus in the south-facing window in a cool bedroom, or the west-facing window in the front bedroom, also kept cool. Cool temps do help control parasites, but the light really doesn’t matter because the cactus are sort of dormant. Then again, the cactus did fine with no parasite issues until last winter, and only a few at that. Cactus don’t like to be bothered with sprays over the winter. At least that is my opinion.

Anyway, I will close for now. I have two posts in the making. One about Euphorbia (wildflowers) and the other about the Symphyotrichum species on the farm. I am waiting for the Euphorbia dentata and E. davidii seeds to dry which will determine the species. At least I hope. Both genera have been quite entertaining.

Until next time, be safe, stay positive, and always be thankful!

 

Fall 2020 Update Part 5: The Mammillaria Group

Part of the cactus collection in front of the sliding door in the dining room on 11-1-20, #754-6.

Hello everyone! I hope this post finds you well. This post is about the Mammillaria species in my small collection of cactus. Mammillaria species come in all shapes and sizes and are very easy to grow and some flower off and on throughout the year. I took most of the photos in this post on October 15 as I was bringing the plants inside, but I had to take a few more on November 1 and 6… The longer it takes to finish this post the more photos I will probably take because of the flowers…

Plants of the World Online currently lists 164 species in the Mammillaria genus, which is up two from my last update. Although The Plant List is no longer maintained, even though it is still online and viewable, listed 185 accepted species, 93 accepted infraspecific names (varieties and subspecies), a total of 519 synonyms, and 448 unresolved names. So many species were given a multiple of scientific names over the years and it was quite an undertaking to resolve the issue. It will no doubt be a continual work in progress, even as new species are added. The Mammillaria genus alone has 20 synonyms… That is 20 previous genera whose species have been transferred to Mammillaria or attempts made to relocate them.

So, why do I like Mammillaria species? For one, there are a lot to choose from, they are easy to grow, they come in a wide variety of sizes and shapes, many freely flower, and some are just downright weird. All Mammillaria have one particular thing in common that makes them stand out. They have pronounced tubercles arranged in a particular manner, kind of looks like they are spiraling upward… If you have a cactus with pronounced tubercles, it is very likely a Mammillaria.

If you want further information about any of the Mammillaria in this post, or to see more photos, click on their name under the photos in green. That will take you to their own page.

Here we go…

<<<<Mammillaria decipiens (subsp. camptotricha)>>>>

Mammillaria decipiens (subsp. camptotricha)(Bird’s Nest Pincushion) at 1 3/4″ tall x 4 1/4″ wide on 10-15-20, #747-64.

I brought this AWESOME Mammillaria decipiens subsp. camptotricha (Bird’s Nest Pincushion) home from Wal-Mart in March 2018 because it was weird and I didn’t have one. It has done very well over the summer and the tallest plant in the pot was 1 3/4″ tall and the cluster measured 4 1/4″ wide on October 15. Like all cactus, they swell and shrink as water is available. I watered the cactus the day before I brought them inside because I thought they would swell somewhat before I took measurements. Apparently, I should have done it several days before that… Sunday, as I was taking photos of few of the Mammillaria with flowers, I noticed the biggest one in this pot looked bigger than before. SO, I went and got the tape measure and it was 2″ tall! GEEZ! That’s 1/4″ taller than it was on the 15th!

That isn’t the first time that happened. When I was writing the post Cactus Talk & Update… OUCH! in December 2018 several had done that. They hadn’t been watered since October but they were swelled up.

Getting back to the Mammillaria decipiens… It was cramped up in a 2 3/4″ diameter pot when I brought it home and the cluster of plants was 1 1/2″ tall x 3″ wide. The pot was literally bulging and the plants were hanging out over the top somewhat.

After doing a little research, I found out this cactus was a subspecies called Mammillaria decipiens subsp. camptotricha. The species has 5-11 radial spines per tubercle that are a whitish color and the spines are shorter. The subspecies have 4-5 radial spines per tubercle that are longer and bristly… Describes the one I brought home perfectly. BUT, “those in charge” have decided the subspecies is a synonym of the species. HOWEVER… Since the subspecies name was validly published in 1997, I can go ahead and use it if I choose. 🙂

This species got around A LOT and has 19 synonyms covering seven genera…

<<<<Mammillaria elongata>>>>

Mammillaria elongata (Ladyfinger Cactus) at 6 1/8″ long/tall x 7″ wide on 10-15-20, #747-66.

Hmmm… As you can tell, the Mammillaria elongata (Lady Finger Cactus) is doing well. This has been an interesting cactus and I have had no issues with it. We got off to a rocky start but that was my fault. This plant, or cluster of plants, was stuffed into a small pot which I accidentally knocked off on the floor a few days after I brought it home in March 2018. Of course, most of the offsets fell off. I stuck them back in the small pot the best I could at the time. It had no side effects and didn’t even get upset. To say this species freely offsets would be an understatement. Even the kids have kids…

On October 15 when I brought the plants inside, the longest or tallest, umm… The main stem in the center, the mother plant, measured 6 1/8″ long, or tall, whichever you prefer. The entire cluster was 7″ wide. After I remeasured the Mammillaris decipiens I wondered about this plant. In fact, last year it was over an inch longer in November than it was in October, up to 7 3/8″! This time it is 6 1/8″ long??? I remeasured it again when I was putting the measurements on the journal and it definitely was 6 1/8″. So, for the heck of it, I remeasured it AGAIN as I am writing this post. Hmmm… 7 3/4″!!! Believe it or not, I do know how to use a tape measure and I am not going to fall for this Mammillaria conspiracy. They did this to me last year…

<<<<Mammillaria hahniana>>>>

Mammillaria hahniana (Old Lady Cactus) at 3 5/8″ tall x 3 3/8″ wide on 10-15-20, #747-67.

Several Mammillaria species have a lot of wool like the Mammillaria hahniana (Old Lady Cactus). I have had this cactus as a companion since I brought it home from Wal-Mart on February 1, 2016. It was only 1 7/8″ tall x 23/8″ wide when I brought it home now it is 3 5/8″ tall x 3 3/8″ wide. NO, I am not going to measure it again to make sure…

Mammillaria hahniana (Old Lady Cactus) on 10-15-20, #747-68.

The Mammillaria hahniana is quite a bloomer and may surprise you anytime throughout the year. Most Mammillaria species are sort of concave at their apex and their spines just kind of unfold as they grow. Mammillaria hahniana is sort of flat-topped and you can clearly see how concave it is in the center. This species is rather globe-shaped when young but can become more columnar with age. Over time they can form good-sized colonies but I don’t think they divide dichotomously.

Mammillaria hahniana (Old Lady Cactus) on 11-6-20, #755-1.

I had to take the above photo on November 6 because it has more buds. It will continue growing more, maybe in 2-3 rows. Llifle (Encyclopedia of Living Forms) lists several subspecies and varieties of Mammillaria hahniana but none are currently accepted even though they were once validly published. They all have certain peculiarities in the quantity and size of spines (central and/or radial), wool, flower color, etc. One even has white flowers. While it may be true they are the same species, these characteristics set them apart so I personally think the intraspecific names should be used to distinguish them from one another. When young, they might look very similar, but these different “features” become more pronounced with age.

<<<<Mammillaria karwinskiana>>>>

Mammillaria karwinskiana (Silver Arrows) at 3 5/8 tall x 3″ wide on 10-15-20, #747-69.

The Mammillaria karwinskiana (Silver Arrows) is a great little cactus that has gotten more wooly since I brought it home from Lowe’s on 9-21-18. It was 1 7/8″ tall x 2 3/16″ wide when I brought it home and now it is 3 5/8″ tall x 3″ wide. If you find this plant at Lowe’s or Wal-Mart it is likely to be labeled Mammillaria nejapensis which is a synonym. In fact, this species has 60 synonyms!!! Ummm… There were only 45 the last time I updated its page last December. GEEZ!!! Where did they all come from? OH, I know… POWO has been uploading a lot of names from the International Plant Names Index (IPNI) they didn’t have in their database. Maybe that’s why…

Mammillaria karwinskiana (Silver Arrows) with lots of wool for the winter on 7-15-20, #747-70.

The tufts of wool on the Mammillaria karwinskiana reminds me of tiny rabbit’s feet (you know, the rabbit’s foot keychains).

Mammillaria karwinskiana (Silver Arrows) with flowers on 11-1-20, #754-2.

It started flowering more shortly after I brought it inside. I am glad its flowers aren’t pink… Maybe this one is a guy.

<<<<Mammillaria muehlenpfordtii>>>>

Mammillaria muehlenpfordtii (Golden Pincushion) on at 4 1/8″ tall x 3″ wide on 10-15-20, #747-71.

I really like this Mammillaria muehlenpfordtii (Golden Pincushion) with its club-shape. I brought it home from Lowe’s when it was 3 1/4″ tall x 2 1/8″ wide in September of 2018. It had fallen over on the discount rack and was completely out of its pot. I picked it up and looked at it, put it back in its pot, then put it in my cart. There was barely any soil left because it had fallen out and onto the floor. This plant likely would have been thrown out and I certainly couldn’t let that happen… I liked its shape, its silver-bluish-green color, and the combination of very long and short spines. Sounded like a win-win for both of us so I bought it home.

The label said it was a Mammillaria celsiana but that species has been determined to be a synonym of Mammillaria muehlenpfordtii. This is one of several Mammillaria I now have in my small collection that divides dichotomously. That means the plant itself becomes two, then two becomes four, and so on. Well, the information says they do that when they “mature” which I have no idea when that will be. 🙂 Until they divide, they are said to be a solitary species. It doesn’t seem to mind its neighbors, though. They are always teasing the cats, trying to get them to jump on their table…

Mammillaria muehlenpfordtii (Golden Pincushion) from the top on 10-15-20, #747-72.

Information I have read says this is a summer bloomer but it is flowering now like it did last October. If it bloomed in the summer I missed it. Some Mammillaria flower just about anytime during the year. I told him “guys aren’t supposed to like pink.” He replied, “Who said I am a guy?” GEEZ! Some Mammillaria species are a bit of a smart aleck…

<<<<Mammillaria mystax>>>>

Mammillaria mystax at 2 3/4″ tall x 2 3/4: wide on 10-15-20. #747-73.

The Mammillaria mystax is a very neat and tidy cactus that hails from central and southwest Mexico. Ummm… There is still no common name given for this cactus. It has done very well since I brought it home from Lowe’s on September 21, 2018. It has grown from 1 3/4″ tall x 2 1/4″ wide to 2 3/4″ tall x 2 3/4″ wide. Even in nature, this species only grows to 6-8″ tall.

I think it is odd how the central spines close to the top are longer than the central spines farther down. Do they shrink as the plant grows or does it grow longer spines as it matures? I am learning that some species of Mammillaria change quite a bit as they age which led to many subspecies and variety names. I know, I know… I am repeating myself. Mammillaria have a tendency to make one talk to themself.

Mammillaria mystax has 28 synonyms now. The featured image on Llifle (Encyclopedia of Living Forms) for Mammillaria mystax shows a cactus that was formerly Mammillaria casoi with long, entangled spines… Supposedly, this species is highly variable. Hmmm… I don’t get it but I guess I don’t have to understand to be confused. 🙂

Mammillaria mystax from the top on 10-15-20, #747-74.

Hmmm… Still, no sign of flowers or buds but it is still a neat plant. Look at those spines! I like it because it is such a neat little ball of thorns plus I have to find out what this one will do as it matures…

<<<<Mammillaria plumosa>>>> 

Mammillaria plumosa (Feather Cactus) at 1 3/8″ tall x 3 1/4″ wide on 10-15-20, #747-75.

The Mammillaria plumosa (Feather Cactus) is quite a neat clump of fuzz. I bought this cactus from an Ebay seller in September 2018 and I will never forget how it arrived. It was like a little ball all wrapped up in toilet paper. The cluster was only 2 1/4″ wide and the largest plant, the big one in the middle, was only 3/4″ tall. It has done quite well and now the biggest plant is 1 3/8″ tall and the cluster is 3 1/4″ wide. Or at least it was on October 15. It is a VERY slow spreader and I think I can barely see two very tiny offsets starting to peak through.

Mammillaria plumosa (Feather Cactus) on 11-6-20, #755-3.

I took a couple more photos of the Mammillaria plumosa to show its flowers.

Mammillaria plumosa (Feather Cactus) on 11-6-20, #755-4.

This hole has been here for a while and I think it is where a flower was last year. Maybe I need to comb it. 🙂

If you ever get a chance to get one of these, I think you will like it. Check on Ebay.

<<<<Mammillaria pringlei>>>>

Mammillaria pringlei (Lemon Ball Cactus) at 5 3/4″ tall x 2 1/2″ wide on 10-15-20, #747-76.

The Mammillaria pringlei (Lemon Ball Cactus) is the third oldest Mammillaria in my collection. I brought it home from Lowe’s on April 24, 2017, but apparently, I didn’t measure it until October 17 when I moved the plants inside for the winter. At that time, it measured 4 1/2″ tall x 3 1/2″ with the spines. Since 2018, I always measure the cactus body and ignore the spines he best I can. Anyway, this cactus always does well and on October 15 it measured 5 3/4″ tall x 2 1/2″ wide. Hmmm… That is the same width as last year BUT I am not going to remeasure it now because I have a sneaky suspicion it will be different. I don’t want to get caught up in remeasuring the Mammillaria again, even though I am curious… Maybe I can do it when they are sleeping so they won’t say, “AH HA! I knew you couldn’t resist.” 🙂

Mammillaria pringlei (Lemon Ball Cactus) from the top on 10-15-20, #747-77.

Mammillaria pringlei is quite a bloomer. It flowers off and on during the summer but really puts on a show in the fall.

Mammillaria pringlei is one of the only species of Mammillaria with yellow spines. They look more white in the photo because of the light.

Mammillaria pringlei (Lemon Ball Cactus) on 11-1-20, #754-3.

I took another photo of the Mammillaria pringlei on November 1. I just had to do it. She asked, “where is your tape measure? Hiding in your pocket?”

This species was once considered a subspecies of Mammillaria rhodantha (next one on the list) then included in the Mammillaria rhodantha Group…

<<<<Mammillaria rhodantha>>>>

Mammillaria rhodantha (Rainbow Pincushion) at 4 1/4″ tall x 2 5/8″ wide on 10-15-20, #747-78.

Mammillaria rhodantha (Rainbow Pincushion) is quite a cactus! Its reddish spines make it a very attractive show-stopper. This was one of my first cactus from Wal-Mart when I started rebuilding my collection of plants in 2016. Until then, I previously had quite a few succulents but not that many cactus. I realized that many succulents I had in Mississippi where I had five sunrooms did not like the low light during the winter here. SO, when I started collecting plants again I went for more cactus because they can handle low light during the winter. I didn’t measure the Mammillaria rhodantha when I first brought it home from Wal-Mart on February 1, 2016, but it was 3 3/4″ tall x 3″ wide (including the spines) on October 17. On October 15 when I brought the plants inside it measured 4 1/4″ tall x 2 5/8″ wide. Hmmm… That is a little shorter than last October when it measured 4 1/2″ tall. Like I mentioned, that is probably because I watered the cactus the day before and they hadn’t “swelled” yet. Even in the wild, Mammillaria rhodantha only grows from 6-12″ tall, so it likely grows fairly SSSSLLLLOOOOWWWW.

The species is variable and some Mammillaria rhodantha have yellowish or whitish spines.

Mammillaria rhodantha (Rainbow Pincushion) from the top on 10-15-20, #747-79.

The Mammillaria rhodantha typically flowers from spring through fall, but this one didn’t flower well until last year. It seemed to be loaded with buds at times but they never grew or opened. Other species in my collection start flowering in one spot then kind of go around the circle. This one will produce buds but the flowers open without a system.

My last update of this species own page was in November 2019 when Plants of the World Online listed 115 synonyms of Mammillaria rhodantha. Now there are 132!!!  78 species are other Mammillaria that were decided were actually Mammillaria rhodantha. There are 35 varieties, subspecies, or forms of Mammillaria rhodantha named that were once valid accepted names. An additional 54 are from when some of those infraspecific names were species in other genera as well as Mammillaria, some fairly recent and some very old names. That doesn’t include names that were not validly published… Mammillaria pringlei was also once considered a subspecies of Mammillaria rhodantha, and apparently, there are variants of it with yellow and whitish spines… Hard to explain it, but there are, or were, six other genera that many species of Mammillaria were in at one point. Heck, most of the older named species in any genera of cactus started out in the genus simply called Cactus

Mammillaria vetula (subsp. gracilis) at 1 3/8″ tall on 10-15-20, #747-82.

The Mammillaria vetula (subsp. gracilis) (Thimble Cactus) is hanging in there to be a good parent. Some of its kids stayed attached better the past summer and the ones that fell off are taking root. This is “one of those” you have to handle with care but not because of its spines. The offsets fall off very easily which is why one of its past scientific names, “fragilis”,  was very appropriate. I had a fairly large pot of this one before, but I hadn’t really been to Lowe’s or Wal-Mart that much to find another one. When I did go to Lowe’s and was looking for one like before, I choose the “Arizona Snowcap’ (below) instead. Then when I went to Wagler’s Greenhouse to take plants in September 2019, I noticed a very small cactus with a few tiny offsets sticking out of it. I looked at it and realized it was a Mammillaria but it didn’t quite look familiar. Well, I brought it home and it turned out to definitely be a Mammillaria vetula subsp. gracilis. I was always used to seeing them available in clusters not as a single specimen. It did perfectly fine over the winter and the next summer and grew quite a bit, well, the offsets did. By the time I moved the plants inside for the winter, most of its offsets had fallen off. Then it was a little plant AGAIN! Fortunately, as I said, most of the offsets it grew since then have managed to stay attached. It measures only about 2″ tall which is pretty good considering… Umm… Considering it was 2″ tall last October. 🙂 Actually, to be honest, it was only 1 1/2″ tall on October 15 but I did measure it again a few days later and it had swelled to ALMOST 2″. 🙂 🙂

I had to get another shot of this plant on November 6 because it was waving its flower at me. It wants me to also tell you about the marble in its pot. After I brought it home from Wagler’s it kept growing toward the light and almost fell over SO, I put the marble next to it to hold it up. I was going to take it out of the pot, but apparently, it got so attached to the marble it wanted me to leave it. I guess it is like a pet rock or maybe it is afraid it will need it again…

Plants of the World Online lists Mammillaria vetula subsp. gracilis as a synonym of Mammillaria vetula (1832) even though there are differences. One difference is that Mammillaria vetula has 1-2 central spines and 25 radial spines. The subspecies does NOT have central spines. I choose to continue to use the subspecies name because it was validly published and accepted in 1997. It replaced the name Mammillaria gracilis (1838). The industry still sells this plant as Mammillaria gracilis var. fragilis which was named and accepted in 1929.

Mammillaria vetula (subsp. gracilis) ‘Arizona Snowcap’ at 1 1/2″ tall on 10-15-20, #747-80.

The Mammillaria vetula (subsp. gracilis) ‘Arizona Snowcap’ did great over the past summer and now, FINALLY, is looking like this cultivar is supposed to again. When I found this cluster at Lowe’s on July 18, 2018 it was a 2″ tall x 5″ wide cluster of balls hanging over the sides of a 3 1/2″ diameter pot. The reason I chose this cultivar over the regular Mammillaria vetula subsp. gracilis was because many of the balls were covered with thick, white spines and I hadn’t seen any like it before. Well, it was just flat neat! I brought it home and took photos. Of course, I put the cluster in a larger pot. Over the next summer, 2019, the plants that were more white died off!  After I moved the plants inside for the winter I removed the dead plants and kind of spruced up the pot a little.

Fortunately, over the summer, the cluster is looking GREAT! As you can see in the above photo, one of the plants has a circle of buds.

I took another photo on November 6 after most of the flowers had opened. It is really neat to see such a small plant have a circle of flowers.

According to LLIFLE (Encyclopedia of Living Forms), this cultivar is a monstrous form, or mutation, of Mammillaria vetula subsp. gracilis that is not found in the wild. They say it is of garden or nursery origin and perhaps a hybrid…

Well, that’s it for the Mammillaria update and it only took about three days to finish. Seems like a week! 🙂 I can get the remaining 10 cactus and succulents in the next post.

Until next time, take care, be safe, stay positive, and always be thankful! I hope you are all doing well…
