Mature plants of this species are striking in appearance with many leafless stems rising from a single root crown with a density similar to that of horsetails. Like many desert perennials, this shrubby, leafless milkweed bears leaves only after rain. The long greenish-white stems occur in clusters. Whitish-green flowers bloom in terminal clusters and are followed by narrow, milkweed pods.
