Description

Haworthia angustifolia is a small succulent that forms rosettes of long, narrow, pale green leaves that become brownish in full sun. It is often confused with Haworthia chloracantha, but it has softer leaves with smaller and closely spaced marginal teeth. The rosettes grow up to 3.2 inches (8 cm) in diameter, slowly offsetting to form small clumps. Leaves are up to 4 inches (10 cm) long, up to 0.4 inches (1 cm) wide, and have a whitish terminal bristle. Flowers are white, pinkish or reddish and appear in spring on slender, usually unbranched, up to 1 foot (30 cm) tall inflorescence.

The specific epithet "angustifolia" means "narrow-leaved" and derives from the Latin words "angustus," meaning "narrow" and "folium," meaning "leaf."

How to Grow and Care for Haworthia angustifolia

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 angustifolia 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: Vegetative propagation, especially by offsets, is the quickest and most common method of propagating Haworthias. They can also be propagated by leaves and seeds.
