Windowed rosette succulent, usually prolifically clumping, from the Eastern Cape in South Africa. This plant is similar to H. cooperi, another Haworthia with windowed leaves, and occupies much of the same territory in habitat. The leaves are pale green but they may turn dramatic orange or yellow colors when stressed. Its habitat may be a summer rainfall zone, but this plant does well in our winter rainfall climate. The roots are quite shallow, so avoid deep pots. Provide strong light for the best, most compact form and strongest color.

The former H. planifolia is now considered to be a form of cymbiformis. Natural hybrids are know to exist with H. angustifolia and H. cummingii. The former H. cuspidata is related to cymbiformis, and is treated by the CoL as a synonym of Star Window Plant (Haworthia cymbiformis var. cymbiformis), but it may in fact be a hybrid between cymbiformis and retusa. Some of the images on this page (and the page for var. cymbiformis) may be cuspidata. A number of other varieties have been described.
