Haworthia lockwoodii Archibald
Haworthia inconfluens var. lockwoodii, Haworthia mucronata subsp. lockwoodii
This species is 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 sun, most Haworthias are adapted to thrive in partial shade. Place the potted H. lockwoodii 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. lockwoodii can withstand temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.
Watering: During the hottest summer months, when Haworthias are mostly dormant, water just enough to keep the leaves from shriveling. From fall to spring, when growth is most active, water H. lockwoodii thoroughly, then wait until the top of the soil dries out before watering again. Water the plants less during the winter when their growth slows down significantly.
Fertilizing: Haworthias do not require much fertilizer but 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, H. lockwoodii 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. Remove a healthy leaf from the rosette along with a slight bit of attached stem tissue. Allow the leaf to callous over for several days, and then put in a container with a well-draining soil mix. Sow seeds in spring or fall in a well-draining soil mix.
