Crassula cremnophila van Jaarsv. & A.E.van Wyk
Common Names
Miniature Crassula
Family: Crassulaceae
Subfamily: Crassuloideae
Genus: Crassula
Description
Crassula cremnophila is a small, slow-growing succulent rarely seen in cultivation. At first sight, you could think it is Crassula hemisphaerica, but the inflorescences are rounded, and the flowers in the thyrse are much larger than those of C. hemisphaerica. The flower color is white or pink. There is a row of densely stacked white hairs on the leaf edges, so it seems that the leaves have a white rim. Leaves can partially get a reddish glow when the plant gets a lot of light and is sparingly watered.

Hardiness
USDA hardiness zone 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 Crassula 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.
Crassulas are generally started by division, offsets, or leaf cuttings. Plants can be easily propagated from a single leaf: sprout leaves by placing them into a succulent or cacti mix, then covering the dish until they sprout.
Repot as needed, preferably during the warm season. To repot a succulent, 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.
