Genus: Crassula


Crassula perfoliata var. minor, also known as Crassula falcata, is a succulent plant that grows up to 2 feet (60 cm) tall. It is an attractive and interesting plant when not blooming, but it is a show stopper when the bright red flowers emerge. Leaves are usually gray-green, sickle-shaped, up to 4 inches (10 cm) long, and up to 1 inch (2.5 cm) wide. They are arranged in overlapping pairs along a usually unbranched stem. Tiny scarlet red flowers are massed together in very showy, dense clusters that rise above the foliage in mid-summer. They open slowly and last for nearly a month when in full bloom.

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.
