Yucca constricta known by the common name "Buckley's yucca," is a plant in the family Asparagaceae. It is found in rocky limestone hills of central and eastern Texas, and also in Coahuila, Mexico.
Yucca constricta is usually acaulesent (trunkless), sometimes growing in clumps, spreading by trailing stems. Flowering stalks reach as high as 50 cm (20 inches) with pendent, greenish-white flowers. Fruit is a dry capsule with shiny black seeds.
