Key Lime Pie
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.
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.
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 took 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 have 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!
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.
