Oxalis purpurea is a long blooming winter growing dwarf geophyte seldom higher than 6 or 7 cm. Stemless perennial with leaves divided into 3 broadly heart-shaped leaflets that have fine hairs on the margins and are purple beneath, developing black streaks when dry.

Flowers always have a yellow throat. Flowers start to appear from early winter (May in SA) and will usually keep flowering until the plants go dormant. The fruit is small (size of a match head) and contains many tiny seeds which are dispersed by explosive dehiscence.

Distribution
Throughout the winter rainfall parts of South Africa, from Namaqualand to Caledon in the Overberg and into the Eastern Cape.

Habitat
Widespread on flats and slopes. Ittends to proliferate in disturbed areas like along the edges of paths and roads.
