Crassula setulosa Harv.
Hairy Cushion Crassula
Crassula setulosa var. setulosa, Crassula setulosa f. setulosa, Crassula bloubergensis, Crassula impressa, Crassula scheppigiana, Crassula stachyera var. pulchella
Crassula setulosa is an attractive, flowering, dwarf, cushion-succulent. It grows naturally as a dense mat, forming a convex cushion, sometimes up to 16 inches (40 cm) wide and up to 4 inches (10 cm) tall (up to 10 inches/25 cm in flower). The species is very variable in appearance throughout its distribution especially with regard to its leaves which vary in size, shape and hairiness, but are typically up to 0.8 inch (2 cm) long and up to 0.4 inch (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 leaf surface but hairless forms also occur. Leaves vary in color from bright green to grey-green in the very hairy forms. Depending on the form, flowers appear in midsummer through to autumn. They are small and cup-shaped with petal tips spreading from midway up the corolla tube, usually 0.12 inch (3 mm) in diameter, and white often tinged red. They cluster to form a dense inflorescence which can be up to 6 inches (15 cm) high. Flowers develop into small capsules which release fine dust-like seed.
How to Grow and Care
Crassula 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.
Crassula 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… – See more at: How to Grow and Care for Crassula.
