Yucca filamentosa, commonly known as Adam's needle, is a medicinal plant native to eastern North America.[1]

Usually trunkless Yucca filamentosa is a multisuckering plant with heads of 30 inch (75cm) long, filamentous, blue green strappy leaves. The plant is fully hardy. Yucca filamentosa is readily identified from other Yucca by white threads (filaments) on the leaf margins. See image [2]

Flower stems up to 10ft (3 metres) tall bear masses of pendulous cream flowers, in summer.
