Streptocarpus rexii

The original Cape primrose: a rosette of long, crinkled leaves with pale mauve to white trumpet flowers, and a parent of most hybrid Streptocarpus. It grows on shaded forest banks and rocks in eastern South Africa and wants mild temperatures, shade and steady moisture.

Where it grows wild

Shaded, humid forest floors, stream banks and mossy rock faces in coastal and Afromontane forest. Generalised from the genus and the measured sites.

Only four records carry elevations, from about 100 to 1,680 m; populations range from near the coast into the escarpment forests.
