Elevation:: 3,000 ft – 8,000 ft

A stout, low yucca with broad, stiff, blue-green sword leaves edged in curling fibers, topped in spring by dense clusters of waxy cream flowers. Its large fleshy, banana-like fruits were an important traditional food across the Southwest.

Care · tuned to the Southwest

Water

Very drought tolerant; needs essentially no supplemental water once established. Overwatering and poor drainage lead to rot. Tolerates monsoon rains well on rocky, draining sites.

Sun & exposure

Full sun; handles intense high-elevation light and reflected heat.

Soil

Prefers dry, rocky, gravelly, or sandy well-drained soil; tolerates alkaline and caliche ground. Avoid wet, heavy soils.

In the Southwest

Cold-hardy across a wide elevation range from desert into piñon-juniper woodland. Leaves end in sharp, rigid spines that easily puncture skin, so site away from walkways. Flowers depend on yucca moths for pollination.

Common problems & fixes

Yucca plant bug — stippled, bleached, speckled leaves
Fix — Blast them off with a hose and spot-treat heavy cases with insecticidal soap; vigorous plants shrug it off.
Root/crown rot from overwatering or poor drainage
Fix — Plant in fast-draining gritty soil, water deeply but infrequently, and never keep the crown wet.

Pets & toxicity

A true yucca containing saponins; ingestion of leaves or flowers can cause drooling, vomiting, or diarrhea in dogs, cats, and livestock, and the stiff spine-tipped leaves cause puncture injuries. Ripe fruit pulp is far less of a concern.

Easy to confuse with

Soaptree yucca (Yucca elata) — narrow leaves and a tall trunk
Yucca glauca — much narrower leaves and slimmer, dry fruit
