Description
Haworthiopsis glauca, formerly known as Haworthia glauca, is a succulent plant with pointed, erect or spreading leaves densely packed along the stems. It is a variable species, particularly in leaf size, shape, and orientation on stems. With age, the stems slowly branch from the base, forming a clump. The leaves are gray-green to blue-green, measuring up to 2.4 inches (6 cm) long and 0.6 inches (1.5 cm) wide.
The flowers are white with brown or green veins and appear in simple inflorescences that can grow up to 12 inches (30 cm) tall from spring to fall.
How to Grow and Care for Haworthiopsis glauca
Light: Although 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 commercial soil formulated for succulents or make your own well-draining potting mix.
Hardiness: Haworthiopsis glauca 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 it just enough to keep the leaves from shriveling.
Fertilizing: Haworthiopsis are slow-growing succulents and do not require much fertilizer. Therefore, feed 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.
