This variety is native to South Africa (Eastern Cape).


Haworthia cymbiformis var. obtusa is a small succulent that forms rosettes of fleshy, smooth, bright green leaves. The rosettes grow up to 4 inches (10 cm) in diameter and offsets at their base to form large clumps. Leaves are boat-shaped with darker longitudinal stripes and transparent tips. Flowers are white to greenish-white with pinkish-brown veins and appear on slender, up to 8 inches (20 cm) tall inflorescences from spring to summer.

This variety is similar to Haworthia cooperi var. truncata, but it has a bit different leaf shape and less transparent leaf tips.

The varietal epithet "obtusa" derives from the Latin "obtusus," meaning "blunt or dull" and refers to the blunt apex of the leaves.

How to Grow and Care for Haworthia cymbiformis var. obtusa

Light: Although some species can grow in full sun, most Haworthias are adapted to thrive in partial shade. Place the potted H. cymbiformis var. obtusa in a bright area with some protection from the hottest rays of the day.

Soil: All Haworthias do not like their roots to remain wet for prolonged periods, so their potting soil should be well-drained. Use a commercial succulent potting mix or make your own.

Hardiness: Haworthias like warmer temperatures in the summer but cool in the winter. However, they do not like being too cold. H. cymbiformis var. obtusa can withstand temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.

Watering: During the hottest summer months, when Haworthias are mostly dormant, water just enough to keep the leaves from shriveling. From fall to spring, when growth is most active, water H. cymbiformis var. obtusa thoroughly, then wait until the top of the soil dries out before watering again. Water the plants less during the winter when their growth slows down significantly.

Fertilizing: Haworthias do not require much fertilizer but for optimum growth, fertilization is a good idea. Feed only with a dilute fertilizer and only during the active growing season.

Repotting: These succulents are generally slow-growing and can stay in the same pot for years. For best health, H. cymbiformis var. obtusa should be repotted into fresh soil every two to three years.

Propagation: Vegetative propagation, especially by offsets, is the quickest and most common method of propagating Haworthias. They can also be propagated by leaves and seeds. Remove the offsets when they have started developing their own roots. Sow seeds in spring or fall in a well-draining soil mix.
