Crassula decumbens

A tiny annual stonecrop with narrow, pointed, often reddish leaves on sprawling or erect stems up to about 15 cm, and small cream to pinkish flowers. It is native to Mediterranean-climate winter-rainfall regions of southern Australia, the Cape of South Africa and central Chile. It germinates with the autumn rains, flowers in late winter and spring, and dies as the ground dries in summer, so growers treat it as a cool-season annual grown from seed.

Where it grows wild

Grows in open, sunny places on sandy, loamy or clay soils: dune slopes, granite outcrops, seasonally damp flats, grassland and disturbed ground such as tracks and lawns. It is a small ephemeral that completes its life cycle in the cool wet season.

Few records carry an elevation; it is mainly a lowland plant of coastal plains and inland plains below about 800 m.
