Description

Haworthiopsis granulata, formerly known as Haworthia granulata or Haworthia venosa subsp. granulata, is a rare succulent with erect stems and stiff leaves with many small tubercles on the lower surface and usually smooth on the upper surface. It offsets slowly around the base to form an impressive clump. Leaves are dark green and take on orange to red tones in full sun. They are narrowly ovate and up to 1.2 inches (3 cm) long. Flowers are greenish-white and appear on long slender stalks from summer to fall.

Etymology

The specific epithet "granulata" derives from the Latin "grana," meaning "grain or seed," and refers to the bumpy texture of the leaves.

How to Grow and Care for Haworthiopsis granulata

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 granulata 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.
