Asparagaceae (asparagus family)
Baja California to Nevada
Yucca schidigera. John Rawlings, ca. 2005

Arborescent, rigid and sharp-pointed leaves, several individuals growing in the Arizona Garden, but unlike Y. schottii has convexo-concave, often twisted leaves, with distinctive coarse, marginal curled filaments. Leaf color varies from blue-green to dark green, and leaf surface from smooth to rough. Leaf length varies from 1.5–3+ feet. The inflorescence, up to 3 ft l., is mostly within the leaves. Its bracted (bracts up to 4 inches long and 1 in. wide), foot-long branchlets (apr. 20 per peduncle) each bear a dozen pendant, flowers, single on up to 1-inch-long pedicels. Each flower has its own small bractlet. Waxy, whitish, campanulate tepals, often maroon-tinted, 1.5–3+ inches long, not joined at their bases, or barely so. One Arizona Garden individual displayed both young fruit (green, 1.5 in. long) and flowers April 15, 2003. Wilson (1938) reported Yucca schidigera in the Stanford Experimental Garden before 1915. (Albert Wilson (1938) Distintive Trees, Shrubs, and Vines in the Gardens of the San Francisco Peninsula.)

It is native to Southwestern California (San Diego Co.), S Mojave Desert, NW Sonoran Desert.

Name derivation: Yucca – Haitian: yuca, or manihot, because young inflorescences sometimes roasted for food; schidigera – from the Latin meaning "bearing a splinter of wood," alluding to the coarse marginal fibers at the edge of the leaf blade [from California Plant Names].
