This species is native to South Africa (Eastern Cape).
Haworthiopsis attenuata, formerly known as Haworthia attenuata, is an attractive, low-growing succulent that forms rosettes of fleshy, dark green leaves with white tubercles. It offsets readily to form clumps. The rosettes grow up to 6 inches (15 cm) tall and up to 5 inches (12.5 cm) in diameter. Flowers are white with green veins and appear on up to 16 inches (40 cm) tall inflorescences, typically from spring to fall, but indoors, they can blossom at any time of the year.
This popular succulent is very similar to and often confused with Haworthiopsis fasciata. However, it can easily be distinguished by its white tubercles that occur on both upper and lower surfaces of leaves, while H. fasciata has tubercles only on the underside.
The specific epithet "attenuata (at-ten-yoo-AY-tuh)" means "thinned, reduced, attenuated" or "weakened, diminished" and refers to the leaves that narrow gradually to the tip. It is the feminine form of "attenuates," perfect passive participle of the Latin verb "attenuo."
How to Grow and Care for Haworthiopsis attenuata
Light: H. attenuata thrives in semi-shaded positions. Brighter light conditions are needed to bring out the leaf coloration. Any window in your home or office is likely to be an appropriate setting for this succulent.
Soil: Use a commercial potting soil specially formulated for succulents or make your own well-draining potting mix.
Hardiness: This plant likes warmer temperatures in summer but cooler in winter. H. attenuata can withstand temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.
Watering: The best way to water this succulent is to use the "soak and dry" method. Get the soil thoroughly wet, and then wait until it is dry before watering again. Water your plant less during the winter when its growth slows down significantly. During the hottest summer months, when H. attenuata is mostly dormant, water just enough to keep the leaves from shriveling.
Fertilizing: H. attenuata is a slow-growing plant, and it does not require much fertilizer. For optimum growth, fertilization is a good idea. Feed only with a dilute fertilizer and only during the active growing season. Avoid summer fertilizing as this succulent is in a 6 to 8 weeks rest period.
Repotting: When the plant has outgrown its container, repot it in the spring or early summer into a new, slightly larger pot with fresh soil.
Propagation: H. attenuata is mostly and easily grown from stem cuttings or by removing offsets from the mother plant. Take stem cuttings during the warmer months. Remove offsets when they have started developing their roots. Spring is the best time to sow seeds.
