Aloe tortuosa, Catevala tortuosa, Haworthia tortuosa, Haworthia ×tortuosa, Haworthiopsis ×tortuosa
The origin of this very variable species is unknown and is supposed to be a hybrid of Haworthiopsis viscosa.
Haworthiopsis tortuosa, formerly known as Haworthia tortuosa, is a small succulent with leaves arranged in a spiral along the stem that grows up to 15 cm tall. Leaves are dull green, rough, sometimes with small tubercles. They are triangular, up to 1.2 inches (3 cm) long, and up to 0.5 inches (1.3 cm) wide. Flowers are white and appear on up to 12 inches (30 cm) tall inflorescences from spring to fall.
The specific epithet "tortuosa" derives from the Latin word "tortuosus," meaning "twisted or winding," and refers to the arrangement of leaves on the stem.
How to Grow and Care for Haworthiopsis tortuosa
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 tortuosa 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.
