Scientific Name
Crassula 'Emerald'
Scientific Classification
Family: Crassulaceae
Subfamily: Crassuloideae
Genus: Crassula
Origin
Crassula 'Emerald' is a hybrid that results from a cross between Crassula barklyi and Crassula susannae. It is most probably a chance seedling in the collection of John Cooper.
Description
Crassula 'Emerald' is a small succulent that slowly forms a dense clump of stems covered with tightly packed emerald green leaves. New shoots appear at the base of the plant, but the growing tips also split up.
The white flowers appear throughout winter in clusters at the ends of enlarged conical stalks.
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 susceptible to mealy bugs and fungal diseases. Overwatering is sure to be fatal as with all succulents, 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, 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.
