Zantedeschia rehmannii

A small pink-flowered calla from the summer-rain highlands of north-eastern South Africa and Eswatini. It grows from a tuber through the warm wet summer and goes fully dormant through the dry, frosty winter, so it should be kept dry while dormant.

Where it grows wild

Grows in grassland, on rocky slopes and along forest margins in the eastern escarpment, often where the soil stays moist during the summer rains.

Mostly upland; the few records with elevations sit around 1,700 m, and climate sites range from about 1,200 to 2,100 m.
