Usually trunkless, it is multisuckering with heads of 75 cm (30 in) long, filamentous, blue-green, strappy leaves.
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, such as Tegeticula intermedia, also use this yucca as a host plant to lay their eggs.
