Yucca elata-Soaptree Yucca
If you've driven through the grasslands of southeastern Arizona, you've
no doubt seen this graceful yucca. It also ranges east through New
Mexico into west Texas, and south into Mexico. This treelike yucca can
grow to 6-20 feet tall, with 2 to 5 branches. A spherical head of
narrow, flexible leaves crowns each branch. The leaves measure from 1 to
3 feet long, with white margins and white marginal fibers. The showy
flower spikes can reach up to 15 feet tall, producing masses of waxy
white flowers in the late spring. Plant Soaptree yucca in full sun and well-drained soil.
Hardy to -10º F, Yucca elata is a great choice for colder
locations. USDA Zone 6.
