About Clematis drummondii Torr. & A.Gray
Clematis drummondii is a species of flowering plant in the buttercup family, Ranunculaceae. It is native to the Southwestern United States – specifically Arizona, New Mexico, and Texas – and northern Mexico. Its common names are old man's beard, Texas virgin's bower, and barba de chivato. This is a white-flowered vine that grows by clambering over other wildflowers, shrubs, and fence rows. Its natural habitats include the Chihuahuan Desert, Sonoran Desert, prairies, and grasslands. The sap of Clematis drummondii is caustic. Despite this, its foliage, stems, and roots can be used to produce dye, as long as handlers take caution during use and avoid breathing in fumes from the plant.
