Crassula perforata is a small, somewhat shrubby and sprawling succulent that grows up to 18 inches (45 cm) tall. Erect first, the fleshy stems become prostrate and woody over time. The leaves are triangular, up to 0.8 inch (2 cm) long and up to 0.5 inch (1.3 cm) wide and grey-green with reddish margins. They grow in opposite pairs. The flowers are very small, star-shaped, white to pale yellow and appear in spring.

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 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 covering 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.
