Description
Yucca rupicola forms colonies of rosettes, lacking trunks above-ground but producing a branched caudex under the surface. Leaves are narrowly lanceolate, slightly succulent, twisted, up to 60 cm long but about 40 mm wide at its widest point. Flowers are pendant (drooping), bell-shaped, white or greenish, and bloom from April through June. The blooming stalk can measure up to 1.8 m tall (6 feet). Fruit is a dry capsule up to 6 cm long that is dull black in appearance.
