Wikipedia: Usually trunkless, it is a multisuckering evergreen shrub with heads 30 inches 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 10 feet tall bear masses of pendulous cream flowers in summer. They are pollinated by the yucca moth Tegeticula yuccasella.
