Streptocarpus dunnii

A striking unifoliate Streptocarpus from the escarpment of Mpumalanga and Eswatini. It produces one huge, hairy leaf and clusters of red to pinkish tubular flowers, and often dies after flowering, so keep seed going. It grows in crevices under rock overhangs and expects a dry, cool winter.

Where it grows wild

It grows in sheltered crevices and at the base of rock faces and overhangs in grassland and forest margins on the escarpment, often partly shaded by the rock itself.

The records lack elevations. The climate sites lie mostly around 1500–1800 m, with some near 600 m.
