Crassula streyi Toelken
Pondo Cliff Crassula, Pondoland Crassula
Crassula streyi is a relatively slow-growing succulent with lax stems and fleshy broadly elliptic leaves. It grows up to 14 inches (35 cm) tall but is usually shorter as the stems sprawl and lose the lower leaves as they get older. Leaves are dark glossy green on the upper surface, while the lower surface is maroon to carmine, giving them a striking appearance. They become longer as they age. The stems sometimes send down roots. Flowers are yellowish-green, star-shaped, and appear in spring arranged in a rounded or slightly elongated thyrse with several dichasia.
USDA hardiness zone 10b to 11b: from 35 °F (+1.7 °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.
