Crassula Expansa subsp. Fragilis

Crassula expansa subsp. fragilis is a low-growing succulent with slender stems and masses of tiny fleshy leaves. It can grow up to 10 inches (25 cm) tall with a spread of up to 20 inches (50 cm). The leaves are flattened discs, sometimes slightly elliptic or obovate. While the leaves are fresh to pale green, the stems are pinkish to maroon. Fine whitish hairs may be scattered along the leaf and stem surfaces.

The flowers are tiny, white, star-shaped, usually 5-petalled, and produced on the tangled cushion of slender stems and small leaves. Typically, they appear from mid-summer to fall.
