|Usually trunkless, it is a multisuckering evergreen shrub with heads of 75 cm (30 in) long, filamentous, blue-green, strappy leaves. It is fully hardy, though in cultivation it benefits from a sheltered position away from winter winds. Y. filamentosa is readily distinguished from other yucca species by white, thready filaments along the leaf margins. Flower stems up to 3 m (10 ft) tall bear masses of pendulous cream flowers in early summer. They are pollinated by the yucca moth Tegeticula yuccasella. Other moth species also use this yucca as a host plant to lay their eggs, such as Tegeticula intermedia.|
Y. filamentosa is closely related to Yucca flaccida and it is possible they should be classified as a single specie
