Maintenance

Drought tolerant. Easily grown in rock gardens. Good barrier plant, but not pedestrian friendly. Selectively prune leaves away from sidewalks or patios to avoid sharp pointed leaves. Flowering stalks can be removed after blooming if desired, however, consider leaving for wildlife habitat. Roots are not happy in heavy soils or moist conditions. Mineral or rock mulches better than organic mulches to allow air to the roots. Trunks can split during prolonged dry spells. Propagation: Seed.

Comments

Blooms May-July. Typically smaller than other Dasylirion species. Often mistaken for a yucca. It has a basal cluster of long blade-like leaves with sharp edges. Small, yellowish flowers grow along a tall stalk. Fruit a 3-winged shell. Attracts bees and hummingbirds.
