This species is native to South Africa (Western Cape). It grows in crevices on sandstone ledges, especially at the edges of plateaux from Cape Peninsula to Still Bay.
Crassula coccinea is a sparingly branched succulent shrub with green, rarely brownish-red leaves arranged in four vertical rows overlapping each other along the stems. The stems are erect to spreading and grow up to 2 feet (60 cm) long, branching from the base. Leaves are flat, ovate to elliptic with ciliate margins, up to 1.4 inches (3.5 cm) long, and up to 0.6 inches (1.5 cm) wide. The old leaves are not deciduous. In summer, the striking flowers appear in dense, flat-topped heads at the end of the stems. The fragrant flowers are tubular, up to 1.8 inches (4.5 cm) long, brilliant red, or rarely white with various tinges of red. Flowers heads are up to 4 inches (10 cm) in diameter.
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Crassulas are easy to grow but 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 cover the dish until they sprout.
Repot as needed, preferably during the warm season. To repot your Crassula, ensure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, removing any rotted or dead roots. Treat any cuts with a fungicide. Place the plant in its new pot and backfill it with potting soil, spreading the roots as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.
