Native to South Africa (Great Karoo).


Haworthia lockwoodii is a small, slow-growing succulent that forms a stemless, solitary rosette. It is very attractive in summer, during the dormant phase when more than half of the leaf dries out and becomes papery white. The wilted leaves cover the rosette almost completely, giving the younger leaves protection from the harsh summer sun. The rosette grows up to 4 inches (10 cm) in diameter. Leaves are yellowish-green with translucent tips market with about eight green to reddish-brown longitudinal lines. They are erect, incurved, up to 2.4 inches (6 cm) long, and up to 1.2 inches (3 cm) wide. Flowers are white, keeled with green veins, and appear in spring on up to 9 inches (22.5 cm) tall inflorescences.

The specific epithet "lockwoodii" honors Stanley George Lockwood-Hill (1903-?), a Haworthia collector who was a magistrate of Laingsburg.

How to Grow and Care for Haworthia lockwoodii

Light: Although some species can grow in full, bright sun, most Haworthias live in more sheltered spots, and they are adapted to thrive in partial shade. Place the potted plants in a bright area with some protection from the hottest rays of the day.

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

Hardiness: Haworthia lockwoodii can withstand temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.

Watering: These succulents are very tolerant of underwatering, but overwatering can quickly lead to rotting. From spring to fall, water thoroughly, then wait until the top of the soil dries out before watering again. During the winter rest period, water just enough to keep leaves from shriveling.

Fertilizing: Haworthias do 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.

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

Propagation: This species is not known to produce offsets, so propagation is by seeds or leaves.
