Repotting Amorphophallus & Oxalis triangularis

Amorphophallus with the Oxalis triangularis subsp. papilionaceae on 6-7-20, #708-1.

Hello everyone! I hope you are all doing well. I have been wanting to move the potted plants to the back deck and front porch but the wind has been crazy! It is a few weeks earlier than I normally do it but I think it is safe. Even if I have to move them back inside it isn’t that big of an ordeal. The plants are looking out the windows and some are coming out of dormancy and beginning to need more water. It is much easier to water over 100 pots outside on the plant tables…

I put the Alocasia on the back deck last week and some of the new plants I brought home from Wagler’s are on the front porch. Last spring I moved the Alocasia to the back deck so I could repot them before I moved them to their usual location. I repotted most of them but they seemed to do well on the back porch so I left them there. The wind wasn’t that bad Sunday, so I repotted the biggest Alocasia ‘Calidora’ that I didn’t get repotted last year. I had bought a large bag of Miracle Grow Potting Soil and I used almost all of it for that one pot. Since it was Easter the hardware store was closed so I couldn’t get another bag. SO, I decided to work on the pot with the two Amorphophallus sp. and Oxalis triangularis subsp. papilionaceae

I brought home the pot from Wagler’s Greenhouse in 2017 with two Amorphophallus and the Oxalis growing in it. I hadn’t been in this pot until July 2018 when I removed the smaller Amorophoallus youngsters. I have been itching to get in the pot to see how big the Amorphallus corms are but I needed to do it when they were dormant. Sunday seemed like the perfect opportunity since the Oxalis had gone dormant over the winter as well… Normally, I keep the Oxalis in this pot watered over the winter and they don’t go dormant.

SOOOOO….. I dug in and removed the Oxalis rhizomes before digging deeper for the Amorphophallus corms. I was totally amazed at how many Oxalis there were. Some species of Oxalis produce bulbs, but as you can see, the Oxalis triangularis is definitely a rhizomatous species…

Besides the two larger Amorphophallus corms, there were seven small ones. It is kind of funny how there is so much confusion about the difference between what a bulb, tuber, corm, rhizome, etc. is. It seems like every time I write bulb, tuber, corm, or rhizome I have to double-check to make sure. I believe the Amorphophallus have corms rather than bulbs. They produce one stem, (which basically replaces the corm as it grows), produce only one petiole, and only one leaf… When they flower, the flower stalk emerges from the dormant corm… The Amprohphallus corm has no eyes like a bulb or rhizome. Of course, if you read information on other sites, you may see them being called bulbs… I suppose it doesn’t matter what you call them as long as you plant them properly.

I was surprised the two larger corms were only 2″ in diameter… I thought they would be maybe twice that size by now. This is actually the first time I have seen them even though I have had the pot since 2017…

Maybe you can’t really tell in the photo, but the corm is kind of concave toward the center…

I found two pots of the same size, 8 1/2″ tall x 9″ diameter, for the larger corms. I put a few inches of potting soil in the bottom of the pots, centered the bulbs with the sprout on top, then filled the pot within an inch or so from the top of the rim.

You can get on several sites online to learn how to plant Amorphophallus corms and so many tell you different things. With so many opinions it may leave you confused. Previously, I had read where bulbs should be planted 6″ below the surface, depending on the size of the corms. I knew from locating them in the pot they were, in fact, 6″ or so deep… SO, that is the depth I returned them at. One site says to plant them twice as deep as the size of the corm but I think that would not do… I planted the smaller corms about halfway down in their pots.

One reason you need to plant the bulbs so deep is because the soil is what will anchor the plant until the roots start to grow. The roots grow from the top of the bulbs AFTER the leaves start growing… The growing plant uses energy from the corm which basically vanishes. SO, you don’t want to water the soil because it could cause the corm to rot…

The top of the corms are slightly concave with a sprout in the center and the bottom is round like a bowl. One video I watched said to plant your bulbs slightly tilted so water won’t collect in the concaved area on the top of the corm (he called them bulbs…). Well, I didn’t do that and just planted them flat. The same video says to use slightly moistened potting soil, while other information says not to water until the stem emerges… The guy in the video also used potting soil with timed-release fertilizer and added more fertilizer below where he put the bulb… Other websites say not to add fertilizer until AFTER the roots start growing.

SO, I used a fresh bag of Miracle Grow Potting Soil, which was slightly damp because it was just opened. I did NOT moisten the soil more. I did not add any more fertilizer… I did NOT water the soil after I was finished…

SO, now the two larger Amorphophallus have their own pots. I put several Oxalis rhizomes in the bigger pots with the Amorphophallus because they look good together. 🙂 I will take the smaller pots to Mrs. Wagler once the plants start growing.

I went ahead and watered the Oxalis rhizomes a little in the bigger pots because some of them had a few sprouts. I didn’t soak the soil, though…

I still have no idea what species of Amorphophallus I have… I would guess probably Amorphophallus konjac.

Now for the Oxalis…

Getting back to the Oxalis triangularis subsp. papilionaceae… There were two larger clusters of rhizomes and quite a few single pieces… They are already beginning to grow…

There several rhizomes similar to the one above and several of them already have leaves… This rhizome is 2 1/2″ long, so put the bottom of it approximately 3″ or so deep in the soil.

I took the large clusters and placed them in the center, with the bottom approximately 3-4″ deep and made sure rhizomes attached to them were verticle. I spaced several of the smaller rhizomes around the bigger clusters in the pot and then covered them all with an inch or so of potting soil.

Little Bit asked if she could help but all she really wanted was a spare hand…

 

Oxalis triangularis on 4-6-21, #790-2.

The local grocery store had a large display of Oxalis triangularis in the early part of March. They had several pots with purple and black leaves and several with solid green. Since I didn’t have one with solid green leaves I brought one home…

Oxalis triangularis leaves on 4-6-21, #790-3.

Oxalis triangularis leaves can be solid green, maroonish, or black and purple… There are several cultivars available and the pots at the grocery store didn’t have labels…

Maybe I should mention a little about the Oxalis triangularis name… Plants of the World Online by Kew lists 22 synonyms of Oxalis triangularis. One of the typical synonyms you see online for these plants is Oxalis regnellii or Oxalis regnellii subsp. triangularis. The name Oxalis triangularis subsp. papilionaceae is even considered a synonym even though the subspecies has much larger leaves… My first experience with Oxalis triangularis was when a friend and fellow plant collector gave me a start in 2012 when I lived at the mansion in Mississippi. It had much smaller leaves so it wasn’t the subspecies… I choose to recognize my purple and black leaved Oxalis triangularis as the subspecies papilionaceae because of its enormous and beautiful leaves. That is OK as long as the name was validly published which it was in 1983. Both the species Oxalis triangularis and Oxalis papilionaceae were named and described by different botanists in 1825. Of course, the name issues could be cleared up if I used the cultivar name ‘Atropurpurea’. 🙂

Plants of the World Online lists 557 species of Oxalis native to nearly every country the world over. Oxalis is a member of the plant family Oxalidaceae (family of Wood Sorrels) with five genera which include mainly annuals, perennials, and subshrubs. Some species are considered invasive weeds…

Spring is a great time of the year to start getting dirty. The garden is ready to be tilled but there is rain in the forecast for Tuesday evening through Thursday. After that, I will till when the soil is ready. I already have the sweet corn seed because I didn’t want the local farmer’s co-op to sell out before I was ready to plant. I will probably have to go to the Greenstreet Market in Clinton to get the green bean and snap pea seeds…

Until next time… Be safe and stay positive. I hope you are all doing well. Don’t forget to always be thankful.

    • Hello Linda! Happy Spring to you as well. Thank goodness there are no freezing temps in our forecast here. Plenty of wind, though, and a thunderstorm is headed our way. It was supposed to be here by 10 PM, but now the forecast says 2 AM… Take care and thanks for the comment!

    I noticed the Rattlesnake Master and Rhubarb are a few inches tall in my small garden plot. I need to borrow the neighbor’s tiller and work the soil in the rest of it. But, it just rained a bunch. That will be a few days yet.

    You actually ‘wanted’ an Amorphophallus?! Oh my! Well, I sort of get it. I acquired a Dracunculus vulgaris, and actually enjoyed growing it, even though it was stinky in bloom. It grows like a weed, so must be contained in a pot. Amorphophallus get big, or at least some species do. Do you know what yours is?

    • Hello Tony! I think it is probably Amorphophallus konjac since they are likely the species most widely available. Just guessing though. I thought the corms would be bigger now, but this was the first time I have seen them. I will check them again next spring to see if they have grown. I had a Dracunculus vulgaris when I lived in Mississippi but I forgot about it and left it behind. I checked on Ebay a few days ago and there weren’t many available, and certainly didn’t want to pay the price. GEEZ! I would be more than happy to send you a corm or two of the Amorphophallus if you want. Take care and thanks for the comment!

        Oh, . . . thank you, . . . but no. I am none too keen on them, although I would grow one if I happen to come across one like I did with the Dracunculus vulgaris that mysteriously appeared in the gardens of a colleague’s home. It would have been nice to get rid of them from the garden, but I still wanted to grow a few within the confinement of a pot. I happened to get a single corm (or whatever it is), and it grew into a few more. They are growing like the weeds that they are at the moment; otherwise I might be able to send you corms. I really do not know because I have not seen them out of the soil since I put them in the pot before last year.

        • Alrighty, I’ll just give the smaller ones to Mrs. Wagler. Have to keep the plant trading deal going, you know. If you happen to run across the Dracunculus a corm or two would be GREAT! THANKS!

            There are a few potted corms here, but I can not send they while they are actively growing. I do not remember when they die back. They stay dormant for quite a while. I might be able to get more from the garden where these came from. I will want to get Cyclamen hederifolium from the same garden anyway, although their dormancy starts earlier. I should remember to let you know when the Drancunculus vulgaris dies back.

            • So they are already up and growing there? I remember seeing several flower beds with Cyclamen when I lived in LA. Made me kind of drool.

                ? Well, yes. They bloom early in summer and then die back, although I do not remember their schedule precisely. It is one of those plants that I do not want in the garden, but would like to grow in a pot just because it is weird and others think it is cool. I really should have gotten more of them. I only got this one because I wanted a corm to get a picture of. After I got the picture, I canned the corm.
                Cyclamen are on a different schedule. In Los Angeles, they are grown as an expensive cool season annual. I rather dislike them like that, not just because they are expensive, but also because they do not last long, and then get discarded. I learned them as a perennial. They die back as the weather gets warm in spring, but then regenerate as the weather gets cool in autumn. Their season is a bit longer here.

                • Well, plants do grow differently in California than they do here. The Dracunculus in Mississippi grew pretty much like the Amorphallus do here only in Mississippi the corm was in the ground. They come up much earlier in California, while here they have just barely started sprouting.
