Streptocarpus cyaneus

A rosette-forming Cape primrose from the escarpment of Mpumalanga, Limpopo and Eswatini. It grows on shaded rock faces and forest banks with summer rain and a cool, dry winter, and it adapts well to a bright window, a humid room and a winter with less water.

Where it grows wild

It grows in shaded crevices of rock outcrops, cliffs and steep earth banks in or beside forest and in mist-belt kloofs, rooting in thin humus.

The recorded sites lie mostly between about 850 and 1,600 m on the eastern escarpment.
