Yucca rostrata
Big Bend Yucca
Description
This Yucca has blue leaves, a tall narrow trunk, and a spectacular summer display of cream white flowers. It is one of the most attractive tree Yuccas. It slowly forms a trunk to 10' tall. The young are usually unbranched; the older have a few branches. Narrow blue leaves can grow up to 2' long but very narrow with a sharp term spine. This Yucca prefers full sun or very light shade and rocky, well drained soil. It is susceptible to grubs. Old leaves persist.
