Haworthia retusa

Star Cactus, Window Succulent
Haworthia retusa

Code: 90658

Price: $7.95

Quantity in Basket: None

Family: Asphodelaceae

Despite the common name Star Cactus, it is not a cactus at all. This is a small succulent that forms star-shaped rosettes of lime green leaves with translucent windows and veining at the tips. These plump "retuse" leaves are curved back allowing sunlight into the plant through its transparent windows. This helps it tolerate low-light conditions allowing interior photosynthesis of the leaves. In its native habitat of South Africa, it's often buried in the ground with just its flattened leaves showing. Small tubular green or brown veined flowers are white on slender 20 inch stalks, blooming typically in late spring to summer. Haworthia are slow growers and in pots can eventually develop into dense clumps. Plant in a gritty succulent potting soil for good drainage. Allow the soil to dry out between watering. It grows best in morning sun or partial shade and is able to tolerate low, indoor light. Haworthias are winter growers and go dormant in the hot summer months when it is important not to over-water. Outdoors, it can handle cool weather but protect from frost.
