Botanical Name: Haworthia retusa var. acuminata
Common Names: Window Haworthia, Star Window Plant
Haworthia retusa var. acuminata is a compact, low-growing succulent native to South Africa, where it inhabits rocky, well-drained areas. It forms tight rosettes of thick, triangular leaves with pointed tips and translucent “windowed” ends that allow light to penetrate deep into the leaf tissue. The leaves are typically bright to dark green and may develop subtle reddish tones under strong light. Slow-growing and highly sculptural, this species is ideal for small containers, windowsills, and succulent collections. Mature plants typically reach 3–5 inches tall and 4–6 inches wide.
Care and Cultivation:
Prefers bright, indirect light to partial sun
Water sparingly; allow soil to dry between waterings
Use a fast-draining cactus or succulent soil mix
Excellent for indoor growing and small containers
Frost Tolerance and Cold Hardiness:
Best suited for USDA Zones 9–11
Not frost-tolerant; protect from temperatures below 32°F (0°C)
Ideal growing temperatures: 60–85°F (16–29°C)
Winter Dormancy and Health:
Growth slows during cooler months
Reduce watering significantly in winter
Maintain bright, indirect light to preserve leaf clarity
Notes:
Distinctive translucent leaf tips create a glass-like effect
Compact, symmetrical rosettes
Slow-growing and long-lived
Excellent choice for collectors and indoor displays
