Haworthia cymbiformis is a small succulent that forms rosettes of light green leaves with darker longitudinal stripes and transparent tips. The rosettes can reach a diameter of up to 10 cm (4 inches) and branch out at the base to form large clumps. The leaves are thick, fleshy, smooth and boat-shaped. The white to greenish-white flowers with pinkish-brown veins appear on slender stems that can grow up to 20 cm high from spring to summer. Cultivation and care of Haworthia cymbiformis Light: Although some species can grow in full sun, most Haworthias thrive in partial shade. Place the potted H. cymbiformis in a bright spot that is protected from the hottest rays of the day. Soil: All Haworthias do not like their roots to remain wet for long periods of time, so the potting soil should be well-drained. Use a commercially available succulent soil or make your own. Hardiness: Haworthias like warmer temperatures in summer and cooler temperatures in winter. However, they do not like temperatures that are too cold. H. cymbiformis tolerates temperatures from 30 to 50 °F (-1.1 to 10 °C). Watering: In spring and fall, when growth is most active, you should water Haworthias thoroughly and then wait until the top of the soil has dried out before watering again. Water your plants less in winter when their growth slows down considerably. In the hottest summer months, when the Haworthias are mostly dormant, water only enough to prevent the leaves from shriveling. Fertilizing: Haworthias do not need much fertilizer, but fertilization is useful for optimal growth. Fertilize only with a diluted fertilizer and only during the active growth period. Repotting: These succulents generally grow slowly and can remain in the same pot for years. However, for optimum health, H. cymbiformis should be repotted in fresh soil every two to three years. Propagation: Vegetative propagation, especially by cuttings, is the fastest and most common method of propagating Haworthias. They can also be propagated by leaves and seeds. Remove the cuttings when they have started to develop their own roots. Sow the seeds in spring or fall in a well-drained soil mixture. Find out more under Cultivation and care of Haworthia. Toxicity of Haworthia cymbiformis Haworthia species are generally non-toxic to humans and animals.
