Haworthiopsis fasciata

The zebra cactus is a small, rare succulent that is native to South Africa. It is a slow-growing succulent but has a long life span of up to 50 years. In the wild, these plants grow in very harsh conditions and are commonly found buried in sand. This plant is a member of the day lily family (Asphodelaceae) and not a cactus, despite the common name. The species epithet, fasciata, describes leaves marked with transverse bands.

For gardeners, they are easy to grow, preferring a well-draining cactus or succulent potting mix. While the plant is somewhat tolerant of low-light conditions, it prefers bright indirect light. Avoid overwatering by allowing the soil to dry out completely between waterings.  Indoor temperatures of 60 to 80 degrees Fahrenheit are well tolerated, and the humidity levels found in most homes are adequate. Avoid exposure to sudden temperature changes or cold drafts. If planted outdoors, it is hardy to USDA zones 10 to 11. Zebra cactus produces pups and offsets, and it may be propagated by separating the pups or removing the offsets from the parent plant. The plant may also be propagated by leaf cuttings, and rarely by seeds.

The zebra cactus forms a tight rosette of stiff, thick, fleshy, linear to narrow, triangular-shaped, dark green leaves with raised white stripes or "zebra stripes"on the outer surface while the upper surface is smooth. The flowers are small, tubular, and white and appear on thin, long stalks. The plant reaches a height of 4 to 6 inches and grows equally as wide. Haworthiopsis attenuata is often mistaken for or mislabeled as this plant– they can be distinguished by the fact that H. fasciata is smooth on the upper surface of the leaf, and the raised zebra stripes are on the outer surface.

Consider the zebra cactus for its attractive foliage and ease of care. It may be used in a terrarium or added to your houseplant collection.

The genus Haworthiopsis was formerly included within Haworthia (q.v. for a discussion of the differences between the genera).

Insects, Diseases, and Other Plant Problems:  Monitor for mealybugs. Leaf spot and fungal diseases can occur when the soil is overly moist. Excessive watering can cause root rot. If it receives too much sunlight, it will turn a deep red showing it is stressed or turn white and dry up. If the leaf patterns fade, this is the result of inadequate light.
