Crassula alba is a rosette-forming succulent that grows up to 20 inches (50 cm) tall, including the inflorescences, freely offsetting from the base. Leaves are spirally arranged, green to yellowish-green, lance-shaped, up to 7 inches (17.5 cm ) long, and up to 0.6 inches (1.5 cm) wide. If you give the plant sun, purple spots appear on the leaves. Flowers are white, pink, or red, have a strong smell of honey, and appear in clusters in summer, forming a flat inflorescence.
The first description in 1775 was for a white-flowered plant, hence the name. Only later were red and pink-flowered plants found.
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 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.
Crassulas 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.
