Sacahuista

Nolina microcarpa

Family:: Asparagaceae
Elevation:: 3,000 ft – 7,000 ft
Bloom:: May – Jul
Region:: Southwest

A large, grasslike mound of long, narrow, arching leaves with finely toothed edges, forming a fountain on rocky Southwest slopes. In early summer it sends up plumes of tiny creamy flowers well above the foliage.

Care · tuned to the Southwest

Water

Very drought tolerant; thrives with little to no supplemental water once established. Overwatering in poorly drained soil invites crown rot. Handles monsoon rain readily on well-drained ground.

Sun & exposure

Full sun to light shade; tolerates reflected heat and high-elevation exposure.

Soil

Prefers rocky, gravelly, or sandy well-drained soils; tolerates poor, alkaline, and caliche conditions.

In the Southwest

Cold-hardy through typical high-desert winters and evergreen. Despite the grassy look it is not a true grass; leaf margins are finely serrated and can cut, though it lacks rigid terminal spines. Comb out or trim dead leaves to tidy the clump.

Common problems & fixes

Largely trouble-free — a very tough, pest-resistant native
Fix — Give it full sun and lean, well-drained soil and otherwise leave it alone.
Crown/root rot from overwatering or heavy clay
Fix — Water sparingly and plant on a mound or in gritty soil so the base never stays soggy.
Tattered, matted old foliage
Fix — Comb out or trim the dead outer blades in spring rather than shearing the whole clump.

Pets & toxicity

Nolina foliage and especially the buds and fruit can be toxic to grazing livestock such as sheep, goats, and cattle, causing liver damage and photosensitization; not a common household-pet hazard.

Easy to confuse with

Sotol (Dasylirion wheeleri) — leaves bear coarse marginal teeth and a spoon-shaped base
Yucca species — stiffer, spine-tipped leaves
