Haworthia mucronata Haw.
Aloe mucronata, Haworthia altilinea var. mucronata, Haworthia altilinea f. mucronata
This species is native to South Africa. It is one of the most widely distributed Haworthias in the Little Karoo and also known from several localities in the Eastern Cape Province.
Haworthia mucronata is a small succulent that forms stemless rosettes of pale green or yellow-green leaves that take on a pinkish blush in bright light. The rosettes grow up to 4.8 inches (12 cm) in diameter, slowly offsetting to form clumps. Leaves are soft, pointed, at first erect, becoming ascending to spreading, incurved, up to 3.2 inches (8 cm) long, and up to 0.5 inches (1.3 cm) wide. They have longitudinal lines, and translucent margins and keel, both often lined with pronounced bristles. Flowers are white with grey-green keels, and appear in spring, spirally arranged on slender, up to 16 inches (40 cm) tall stem.
The specific epithet "mucronata" derives from a Latin word meaning "pointy" and refers to the leaf shape.
How to Grow and Care for Haworthia mucronata
Light: Although some species can grow in full sun, most Haworthias are adapted to thrive in partial shade. Place the potted H. mucronata 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. mucronata 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. mucronata 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. mucronata should be repotted into fresh soil every two to three years.
Propagation: Vegetative propagation, especially by offsets, is the quickest and most common method of propagating Haworthias. They can also be propagated by leaves and seeds. Remove the offsets when they have started developing their own roots. Sow seeds in spring or fall in a well-draining soil mix.
