Yucca aloifolia L.
Aloe yucca, Spanish dagger
Agavaceae (Century-Plant Family)
USDA Symbol: YUAL
Aloe yucca or spanish dagger is a slender-stemmed plant, 6-12 ft. high (sometimes taller) with a stocky, branched or unbranched trunk. The evergreen leaves are thick and stiff and up to 2 ft. long, with tiny, sharp serrations on the margin and a very sharp tip. Whitish, pendulous flowers, about 3 in. wide, occur in erect clusters up to 2 ft. long, and are followed by fruit which becomes pendent. Evergreen shrub or small tree often with stout clustered trunks that are sometimes branched, with sprouts at the slightly swollen base, and with bayonetlike leaves crowded and spreading at top.
Tolerant of salt and suitable for planting along sandy shores, Spanish Bayonet is easily propagated from sprouts. Several cultivated varieties have striped or colored leaves. The fruit is eaten by birds and sometimes by humans, and the flowers can be served as a salad or cooked. Pioneers made rope and string from the fibrous leaves.
