Streptocarpus cooksonii

A Cape primrose relative from KwaZulu-Natal, recorded mainly in the Tugela valley region. Like other South African Streptocarpus it grows in shaded, rocky places in forest patches and kloofs, with a warm wet summer and a cool dry winter, so it wants bright shade, airy media and less water in winter.
