Yucca schidigera, also known as the Mojave yucca or Spanish dagger, is a perennial plant in the asaparagus family native to the southwestern United States and northwestern Mexico. It is most common in the Mojave Desert, but also occurs extensively in the Sonoran Desert and west to the Pacific coast of southern California and Baja California.

Description

Yucca schidigera is a small evergreen tree growing to 5 metres (16 feet) tall, with a dense crown of spirally arranged bayonet-like leaves on top of a conspicuous basal trunk. The bark is gray-brown, being covered with brown dead leaves near the top, becoming irregularly rough and scaly-to-ridged closer to the ground. The leaves are 30–150 centimetres (12–59 inches) long and 4–11 cm (1+1⁄2–4+1⁄4 in) broad at the base, concavo-convex, thick, very rigid, and yellow-green to blue-green in color.

The flowers are white, sometimes with a purple tinge, 3–5 cm (1+1⁄4–2 in) long (rarely to 7.5 cm), bell-shaped and segmented into six parts; they are produced in a compact, bulbous cluster 60–120 cm (24–47 in) tall at the top of the stem. The fruit is an elongate berry, up to 11.5 cm (4.5 in) long.

Distribution and habitat

Yucca schidigera is native to Arizona, Baja California, California, Nevada, and Utah. It is found in the southernmost part of Nevada, in Washington County in Utah, and the northwestern part of Arizona.

It is most common in the Mojave Desert, but is also widespread in the Sonoran Desert and west to the Pacific coast of southern California and into Baja California. Y. schidigera reaches its southernmost extent in the Baja California desert.

In the coastal part of its range, Y. schidigera usually associates with Adenostoma fasciculatum (chamise).

This yucca typically grows on rocky desert slopes and creosote desert flats between 300–1,200 m (980–3,940 ft) altitude, rarely up to 2,500 m (8,200 ft). They thrive in full sun and in soil with excellent drainage. It also needs no summer water. It is related to the banana yucca (Y. baccata), which occurs in the same general area; hybrids between the two are sometimes found.
