Haworthiopsis woolleyi (Poelln.) G.D.Rowley
Haworthia venosa subsp. woolleyi, Haworthia woolleyi, Haworthiopsis venosa var. woolleyi
This species is native to South Africa (Eastern Cape).
Haworthiopsis woolleyi, formerly known as Haworthia woolleyi or Haworthia venosa subsp. woolleyi, is a slow-growing succulent that forms small, solitary to slowly proliferous rosettes of green to brownish leaves. The rosettes are stemless and up to 2 inches (5 cm) in diameter. Leaves are triangular with the upper surface marked with vertical lines, slightly scabrid with raised tubercles on the lower surface, and have margins with small white teeth. Flowers are white and appear in a raceme on a simple long stalk from spring to fall.
The specific epithet "woolleyi" probably honors Charles Hugh Frederick Wooley (1894-1969), a major in the Royal Marines and plant collector in South Africa.
How to Grow and Care for Haworthiopsis woolleyi
Light: Even though most species can tolerate full sun, these succulents thrive in semi-shaded positions. However, brighter light conditions are needed to bring out the leaf coloration.
Soil: Plant your Haworthiopsis in a commercial soil formulated for succulents or make your own well-draining potting mix.
Hardiness: Haworthiopsis woolleyi 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 Haworthiopsis thoroughly, then wait until the top of the soil dries out before watering again. Water your plants less during the winter when their growth slows down significantly. During the hottest summer months, when Haworthiopsis are mostly dormant, water just enough to keep the leaves from shriveling.
Fertilizing: Haworthiopsis are slow-growing succulents, and they do not require much fertilizer. Therefore, feed only with a dilute fertilizer and only from spring to fall.
Repotting: When the plant has outgrown its container, repot in the spring or early summer into a new, slightly larger pot with fresh soil.
Propagation: Haworthiopsis are mostly and easily grown from stem cuttings or by removing offsets from the mother plant.
