Description
Tristagma uniflorum is a small, bulbous perennial that typically grows to about 4 to 10 inches tall. Its foliage resembles that of chives—long, narrow, and slightly arching, with a subtle onion-like scent when crushed. But what truly sets it apart are its striking six-petaled star-shaped flowers that bloom profusely in early to mid-spring. The blooms, usually pale blue to lavender, sometimes white, appear singly on slender stems—hence the species name uniflorum, meaning “one flower.”
Each flower is about 1–1.5 inches across, with a yellow center that contrasts beautifully against the petal color. As the blooms open, they add a light, airy charm to borders, rock gardens, and even lawns. The plant is often used in mass plantings to create a soft carpet of stars.
Growth and Cultivation
One of the best things about Tristagma uniflorum is its resilience and ease of cultivation:
Soil: Prefers well-drained soil but is not particularly fussy about pH or fertility. It performs well in sandy or loamy soils.
Light: Thrives in full sun to part shade. In hotter climates, it benefits from afternoon shade.
Water: Moderate water needs. It's drought-tolerant once established and dislikes waterlogged conditions.
Propagation: Propagates easily by offsets and self-seeding. Bulbs can be divided in late summer or early fall.
