Yucca elata (Engelmann) Engelmann
(Soaptree Yucca, Palmilla)
Family: Agavaceae
Status: Native
Synonyms:
Yucca angustifolia Pursh var. elata Engelmann
This yucca frequently reaches several meters tall and may have
several branches. The inflorescence is a highly branched panicle on tall
scape. The fruit is a dry, brown capsule with three chambers which are transversely
ridged on the inner surface. There are two poker chip stacks of black seeds in each
of the chambers with a septum between the stacks. Some of the seeds are white, perhaps sterile or just a color variation. The long leaves have a white border when young and filamentous strands from the edge, more evident toward the center of the plant. It is not an uncommon sight to see Yucca elata appearing to have been shorn to the stem. Apparently packrats (Neotoma sp.) add the Yucca leaves to their nests.
