This tree-like (arborescent) yucca is from the lower Chihuahuan Desert in Mexico, where huge specimens with five-foot-diameter trunks have been reported. The rigid, olive green leaves grow to 20 inches long, with coarse white fibers on the margins. The unusual flower stalk is pendulous, hanging down from the rosette of foliage. It is very similar in appearance to Yucca periculosa and Yucca decipiens, with the exception of the pendulous flower spike. The large flowers are creamy white. Plant in full sun and provide excellent drainage.
