Yucca faxoniana is a bladed evergreen shrub of the genus Yucca. It is known by the common names Faxon yucca, Spanish dagger, and giant dagger.

Description

The plant generally is a multitrunked shrub 3–10 feet (0.91–3.05 m) in height. They can be single trunked and tree-like to 20 feet (6.1 m) tall. The bladed leaves range from 2 to 4.5 feet (0.6 to 1.4 m) in length. The flowers, ivory to creamy white and bell shaped, are on a flower head up to 2 feet (0.6 m) long.

Flowers, pollinated by moths of the genus Tegeticula, bloom typically in April. The plant produces sweet, pulpy, oblong fruits.

Taxonomy

The species has been called Yucca torreyi – a name given in 1908 by John Shafer. The epithet commemorates John Torrey, a 19th-century American botanist who designated this as a new variety in 1859. Y. torreyi is now regarded as an illegitimate name; however sources differ as to the correct name, using either Yucca treculeana Carrière or Y. faxoniana.
