Sub-category: Asparagaceae family
Usually trunkless, it is a multisuckering evergreen shrub with heads of 75 cm 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 tall bear masses of pendulous cream flowers.
Blooms in early summer. Most commonly found as an ornamental plant in landscaping and gardens.
