Asclepias L. (1753), the milkweeds, is a genus of herbaceous perennial, dicotyledonous plants that contains over 140 known species. It used to belong to the family Asclepiadaceae, but is now classified in the subfamily Asclepiadoideae of the dogbane family Apocynaceae. Milkweeds are an important nectar source for bees and other nectar seeking insects, and a larval food source for monarch butterflies. Milkweed is named for its milky juice, which contains alkaloids, caoutchouc, and several other complex compounds including cardenolids. Some species are known to be toxic. Carolus Linnaeus named the genus after Asclepius, the Greek god of healing, because of the many folk-medicinal uses for the milkweed plants. Species in the Asclepias genus grow their seeds in pods. These seed pods contain soft filaments known as either silk or floss. The filaments are attached to individual seeds. When the seed pod ripens, the seeds are blown by the wind, each carried by several filaments. Info From Wikipedia, the free encyclopedia
