Desert
Natural History:
Native to Northern Mexico, this plant can be found in deserts from Texas to California. Highly prized ethnobotanically, this species of Yucca probably owes its dissemination throughout the Southwestern U.S. largely due to human activity.
Cultivation Notes:
This plant is drought tolerant once established. It is best grown in full sun in rocky, desert soils (3). Under cultivation, it should be planted in soil that has good drainage (4). This species has a moderate growth rate, which can be increased by supplying water from spring through summer, being careful not to over water (2). As with other Yucca species it is susceptible to root damage from beetle larva (1).
Ethnobotany:
The long, broad, and fibrous leaves provide fibers that can be soaked to use for weaving, rope making, sewing, and other fiber arts. The water used to soak fibers contains plant compounds called saponins that can be applied topically as a skin treatment, or used as a cleaner due to its surfactant properties.
