The Story

Plant Bio

Hypoxis decumbens is a low-growing, cormous perennial with pleated, grass-like leaves. It produces a succession of small, star-shaped, bright yellow flowers, each borne on its own slender stalk. Notable for its very long bloom season, from spring through fall in mild climates. Its drought tolerance and preference for well-drained, gritty soils make it ideal for rock gardens, container edges, and xeriscaping.

Uses & Benefits:

Adds bright yellow accents to sunny borders and rock gardens, thriving with minimal care.

Drought tolerant, reduces need for frequent watering.

Provides nectar for pollinators and insects in early summer.

Common Questions

Star Grass questions

What zones can Star Grass grow in?

Star Grass is hardy in USDA Zones 8–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Star Grass deer resistant?

Yes — Star Grass is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Star Grass bloom?

Star Grass typically blooms in spring, summer, fall through mid-summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Star Grass need full sun?

Star Grass does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Star Grass drought tolerant?

Yes — once established (usually after the first full season), Star Grass handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
