Zantedeschia rehmannii normally grows in small groups among rocks on grassy hillsides at medium and quite high altitudes, in semi-shade at forest margins and in sandy furrows. Unlike the other arums, the leaves are lance-shaped and it is also much smaller, varying between 0,2 and 0,6m. It is seldom speckled. Flowers are slender and small and the colour varies between pure white and dark pink. They flower September to February, with a peak in November to January.
Zantedeschia rehmannii, a dainty plant is suitable for the smaller garden. It does equally well in sun or semi-shade.
