Description
Crassula setulosa is an attractive small succulent that grows naturally as a dense mat, forming a cushion sometimes up to 16 inches (40 cm) wide. It grows up to 4 inches (10 cm) tall. This species is very variable in appearance throughout its distribution, especially its leaves, which vary in size, shape, and hairiness. The leaves are typically up to 0.8 inches (2 cm) long and up to 0.4 inches (1 cm) wide, more often than not with a convex upper leaf surface and tapering towards a point. Fine hairs are usually present on the upper surface, but hairless forms also occur. Leaves vary in color from bright green to grey-green in very hairy forms. Depending on the form, flowers appear in midsummer through to fall. They are small and cup-shaped, white often tinged red, and cluster to form a dense inflorescence that can be up to 6 inches (15 cm) high. Flowers develop into small capsules which release fine dust-like seed.
Hardiness
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °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.
