Etymology
The specific epithet "cymbiformis (pronounced sim-BIH-for-miss)" means "boat-shaped" and refers to how the leaves curve inward and come to a point.
Origin
Haworthia cymbiformis is native to South Africa. It occurs on rocky slopes along rivers and streams from Port Elizabeth to East London in the Eastern Cape Province.
Description
Haworthia cymbiformis is a small succulent that forms stemless rosettes of thick, fleshy, pale green leaves with dark longitudinal stripes and transparent tips. It offsets profusely and forms attractive clusters with age. The rosettes can reach up to 3 inches (8 cm) in height and 4 inches (10 cm) in diameter. The leaves are boat-shaped and can measure up to 2 inches (5 cm) long and 0.8 inches (2 cm) wide.
The flowers are tubular, white to very pale pink with brownish-green veins, and appear from mid-spring to early summer on slender stalks that can grow up to 8 inches (20 cm) tall.
How to Grow and Care for Haworthia cymbiformis
Light: Although some species can grow in full sun, most Haworthias are adapted to thrive in partial shade. Place the potted H. cymbiformis 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 can withstand temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.
Watering: In spring and fall, when the growth is most active, water H. cymbiformis thoroughly, then wait until the top of the soil dries out before watering again. Water your plant less during the winter when its growth slows down significantly. When this plant is mostly dormant during the hottest summer months, water it just enough to keep the leaves from shriveling.
Fertilizing: Haworthias do not require much fertilizer, but fertilizing is a good idea for optimum growth. 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. However, for best health, H. cymbiformis 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.
