Asclepias subulata is a species of milkweed known commonly as the rush milkweed, desert milkweed or ajamete. This is an erect perennial herb which loses its leaves early in the season and stands as a cluster of naked stalks. Atop the stems are inflorescences of distinctive flowers. Each cream-white flower has a reflexed corolla that reveals the inner parts, a network of five shiny columns, each topped with a tiny hook. The fruit is a pouchlike follicle that contains many flat, oval seeds with long, silky hairlike plumes. This milkweed is native to the desert southwest of the United States and northern Mexico.
