Usually trunkless, Yucca filamentosa is a multisuckering plant with heads of 30 inch (75 cm) long, filamentous, blue green strappy leaves. The plant is fully hardy. Yucca filamentosa is readily identified from other Yucca species by white threads (filaments) on the leaf margins (see image).
In the wild, Y. filamentosa is native to the southeastern United States, as far west as Louisiana and as far north as Virginia. However, it is widely cultivated and can be found naturalized outside its native range.
Yuccas are useful garden perennials because they bloom at night (nyctinisty). The creamy-white flowers fill with sap and lift petals to the darkening sky then release a sweet odor (which reminds some viewers as smelling of a toilet soap) that attracts the very small pollinator, the yucca moth.
