Crassula cornuta Schönland & Baker f.
Accepted Scientific Name
Crassula deceptor Schönland & Baker f.
Crassula cornuta is a small, succulent perennial, up to 6 inches (15 cm) tall, with silvery-grey leaves that fit tightly together, hiding the stem and making a distinctive column. The flowers are very small and creamy to pinkish in color. They appear in every time of the year when conditions are appropriate, but they tend to be produced mainly during the winter as these are basically a southern hemisphere plants.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Crassulas are easy to grow, but they are susceptible to mealy bugs and fungal diseases. As with all succulents, overwatering is sure to be fatal, so err on the side of too dry rather than too wet. Never let your plant sit in water. If you water from beneath by letting the plant sit in a saucer of water, make sure to pour off any excess water after a few minutes.
These succulents are generally started by division, offsets or leaf cuttings. Crassulas can be easily propagated from a single leaf. Sprout leaves by placing them into a potting mix for succulents, then covering the dish until they sprout.
Repot as needed, preferably during the warm season. To repot your Crassula, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.

Crassula cornuta is a variable species lumped under Crassula deceptor, but in cultivation it often keep the original name to avoid confusion with C. deceptor which itself can be a very variable plant. C. cornuta usually has almost white leaves which are longer and more angular, while C. deceptor has rounded, grayer leaves. However, there is a series of transitional forms and it is almost impossible to tell them apart, so now they are all synonymized with C. deceptor.
