Xerophyllum is a genus of perennial plants from the family Melanthiaceae. The genus is native to North America.[1]

There are two species:[2][3]

Xerophyllum asphodeloides (Pursh) Nutt. - southern Appalachians from Alabama to Maryland; also Delaware + New Jersey
Xerophyllum tenax (Pursh) Nutt. - Alberta, British Columbia, Montana, Idaho, Wyoming, Washington, Oregon, N + W California

Some species formerly placed in this genus have been transferred to others (within the tribe Melanthieae):[2]

Xerophyllum gramineum = Stenanthium gramineum (Ker Gawl.) Morong
Xerophyllum sabadilla = Schoenocaulon officinale (Schltdl. & Cham.) A.Gray

The elongated leaves of X. tenax, commonly known as bear grass, are used for basket weaving by the Native Americans. Xerophyllum asphodeloides also known as turkey's beard is a popular garden plant, producing spikes of white flowers.
