Crassula peduncularis

Purple stonecrop

A tiny annual Crassula (formerly Tillaea peduncularis) of seasonally wet ground in Australia, New Zealand and southern South America. It is not a typical succulent: it germinates when winter rains fill shallow pools and seepages on rock outcrops, flowers in spring and dies once they dry. Grow it as a cool-season annual from seed, in full sun, with wet, bog-like conditions from autumn to spring.
