Crassula plegmatoides Friedrich
Crassula pseudocolumnaris, Crassula arta, Crassula deltoidea
Crassula plegmatoides is a succulent subshrub that grows up to 6 inches (15 cm) tall when in flower, forming light grayish-green columns of thick rounded leaves. The stems are columnar, unbranched (occasionally branched at the base), erect or prostrate, up to 0.6 inches (1.5 cm) in diameter, and completely coated by the close-pressed leaves that form a 4-angled column. It produces open, somewhat hairy heads of cream flowers in late summer or fall.
USDA hardiness zones 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 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, 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.
