Crassula × imperialis
It is thought by some to be a hybrid, but this succulent is probably just a thicker form of Crassula muscosa.
Crassula 'Imperialis' is a small, densely branched succulent with tiny light green to grey-green or brownish-green leaves densely packed around branching, erect to decumbent stem, forming a square mass similar to C. muscosa but thicker. The stems grow up to 8 inches (20 cm) long. Flowers are tiny, pale yellowish-green to brown, and appear in summer and fall.
USDA hardiness zones 9a to 10b: from 20 °F (−6.7 °C) to 40 °F (+4.4 °C).
How to Grow and Care
Crassulas are easy to grow but susceptible to mealybugs 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, ensure 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, and remove 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.
