Adromischus cristatus

ad-roh-MIS-kus kris-TAY-tus

Syn: Adromischus poellnitzianus

Adromischus cristatus (Haw.) Lem. is the accepted scientific name for this plant. It was described by this name by (Antoine) Charles Lemaire in Jardin Fleuriste in 1852. It was first described as Cotyledon cristata by Adrian Hardy Haworth.

Native Habitat: Lower Baviaanskloof and Langkloof west of Humansdorp, Eastern Cape, South Africa. This particular species is easily recognized by its felt-like leaves and tangled, hair-like aerial roots.

 I bought this neat little plant from Lowe’s on April 23, 2017. The label says, “Adromischus cristatus is from Cape Province, South Africa. This attractive plant forms a loose rosette of fuzzy plump leaves, with the tip of each leaf being very undulating and crinkly. Flowers are tubular, whitish with some reddish markings. Protect from frost. Provide filtered light; hardy to 32 degrees F; to 3+” tall.”

Although I have had problems growing succulents with thick, fuzzy leaves in the past, information suggests the Adromischus cristatus is an easy species to grow. I am sure there are “rules” that need to be followed, though.

I decided I need to put it in a larger pot. I can also see that “someone” got a little hungry and took a couple of nibbles.

USEFUL INFORMATION:

Family: Crassulaceae
Origin: Lower Baviaanskloof and Langkloof west of Humansdorp, Eastern Cape, South Africa.
Size: Good question… Dave’s Garden says 12-18”, but I don’t know about that…
Zones: 9b-10b (25-35°F)(from Dave’s Garden)
Temperature Range: They prefer a minimum temperature of 41°F (5°C) but can tolerate short periods down to 20° F about -7°C). Dry soil is a must during cool temperatures.
Light: They prefer light to part shade as the leaves will burn in too much sun.
Soil: Well-draining soil, of course. The faster the better.
Water: They like to be well watered during their growing periods in the spring and fall but the soil needs to dry out between watering. They need much less water during the winter and the leaves will shrivel if it isn’t given enough. I know this because my plant decreased in size after I bought it inside.
Flowers: Information on the internet say they produce white to near white flowers during the summer through early fall.
Propagation: The best method of propagation if from leaf cuttings (and stem cuttings). Cut or twist the leaf and allow it to scab over for a few days then insert the stem end partially into the soil. The leaf needs to be standing upright so the roots will grow downward. The old leaf should not be removed until it has dried up.
Problems: They can be prone to mealy bugs. Overwatering, especially during dormancy (during the winter) can cause rotting.
Maintenance: With age, the center part may become bare. You can remove the stems, or leaves, and restart. Apparently, this plant may branch out and the stems produce aerial roots which make taking cuttings fairly easy. If you are new to this, this will be interesting for you. OH, also information states that these plants like smaller pots and should only need repotting every other year.

As temperatures started getting cooler I knew that soon I would have to bring the cactus and succulents and other potted plants inside for the winter.

 

Adromischus cristatus on 10-17-17, #384-1.

On October 17, 2017, I finally had to bring the plants inside. I always clean the pots off and take the leaves from the trees out of the pots before I bring them in. You have to give your plants a good look to make sure no unwanted pests come in with them. I load all the plants in the back of the pickup and drive to the basement steps. I always like to make sure the outside temps are similar to the basement temperature when I bring them in which is usually around 65 degrees F. year round. Once inside, I take photos and measure the plants. The Adromischus cristatus measured 1 1/2″ tall x 4″ wide. I had put it in a 3 1/2″ tall x 4″ diameter pot earlier because it was outgrowing the small pot I bought it in.

I put this plant and put it on the kitchen windowsill along with several other cacti and the Faucaria tigrina (Tiger Jaws).

It did well on the kitchen windowsill for a while, then the bigger leaves started shriveling and dying. The rest of the leaves started getting smaller, too. It was winter, so I thought it must be going dormant. I gave it a little water because it seemed like it was begging. GEEZ! I thought, “Here we go…” Remember what I said earlier about having issues with succulents with fat, fuzzy leaves during the winter? So, I moved the plant to the plant table in my bedroom with a south facing window.

I am determined this plant IS NOT going to die. I barely give it any moisture, just barely. I sprayed it a few times because the temptation to give it water is crazy. I try not to even look at it. Then one day I noticed something new… HOLY CRAP! It has a baby!

Here is this plant, seemingly barely hanging on for dear life, and it sprouts a baby! In this photo, you can also see the brown “aerial” roots that are a common characteristic of this plant.

I also found out that you should avoid getting water on its leaves during the winter. That means NO MORE misting! So, I will just have to see what happens next and hopefully, when spring finally comes this plant will start growing. Maybe it will flower!

When temperatures finally warmed up, I moved the potted plants from the house and basement outside for the summer.

The Adromischus cristatus definitely looks a lot different than it did last year. The offset is still alive and growing but the main plant… I think I have an idea.

 

Adromischus cristatus (Key Lime Pie) on 6-28-18, #465-1.

Well, I decided to make a change. Since this plant isn’t looking all that swift, I decided to take this plant out of the pot…

 

Adromischus cristatus (Key Lime Pie) on 6-28-18, #465-2.

I removed the offset and then…

 

Adromischus cristatus (Key Lime Pie) on 6-28-18, #465-3.

Then I mixed fresh potting soil with chicken grit and put the main plant deeper in the mix. Then I put the offset in a pot of its own. Normally I mix 2 parts potting soil with 1 part chicken grit and 1 part perlite. I am experimenting with a new potting soil with sphagnum moss rather than peat which seems to have A LOT of perlite already so I just added grit. Cactus and succulent enthusiasts recommend using pumice in place of perlite but I can’t find it locally.

Now we will just have to see what happens. I will keep adding photos and information as time goes by.

I hope you enjoyed this page so far. I will continue adding photos and information as long as I have this plant as a companion.

    Mine has grown a 9″ tall stem. Should I let it grow taller, and should I expect it to flower eventually? Thanks.

    • Hello Lilianne! Mine only grew to 1 1/2″ tall then it went to crap after I brought it inside for the winter. It has not done well this year but it is still alive. If you could send a photo of yours I would like to see it. How long have you had yours? Dave’s Garden says they can grow 12-18″ tall and various websites give other heights. I have no idea when it will flower, though. Thanks for the comment!

  2. How is the plant doing now?

    • Hello Wendy! Well, only the largest plant remains. It has grown a little taller, but certainly, nothing to brag about. A far cry from before. I suppose I need to take an updated photo even though it is a pitiful looking sight. It looks healthy but I have no idea what to do with it. Do you have one? Thanks for the comment!

      • I do have one! I have really bright windows in my classroom and I keep it there. It has a 12” flower stalk on it now and I was searching about the plant’s blooming cycle when I ran across your post. I love the way you post like a little saga for the plant! I got all wrapped up in its destiny lol 😊

        • OH MY GOODNESS! I would love to see the flower! (email to thebelmontrooster@yahoo.com :)) How long have you had yours? I always like to hear from people who have better luck with certain plants than I do. That’s so awesome! I am no expert but I enjoy growing a lot of plants, Cactus and succulents are among my favorite but many succulents don’t do well inside over the winter. Cactus are no problem, though. I am glad you enjoyed my tribute to this nice plant, although I am not sure about its future. Maybe I need some advice from you. 🙂
