Sometimes sold as Crassula portulacea. This is a top-notch houseplant, large container plant, or landscaping shrub in mildest climates. Use only as potted plant in hottest desert regions. The plant has a stout trunk and sturdy limbs, even when small, and stays small in containers. In time, can reach 9 ft. tall and half as wide, but is usually smaller. Leaves are thick, oblong, fleshy pads 1–2 in. long, glossy bright green, sometimes with red-tinged edges. Clusters of pink, star-shaped flowers appear from fall into spring.
