Milkweed, Butterfly – Asclepias tuberosa
Also known as Butterflyweed, this hardy perennial, whose scientific name comes from the Greek god of medicine, is a favorite of butterflies. Unlike other milkweeds this species does not have milky sap. This species has traditionally provided food, medicines and fiber. The clusters of flowers will range from dark orange to white on tall woody stems with smooth shiny leaves that are velvety underneath. These plants grow well in a variety of locations from prairies and open woodlands to roadsides. The seeds are very easy to grow and do well when planted in the fall or when cold-treated for three month prior to planting. Butterfly Milkweed will spread through seed distribution and underground shoots. Monarch Butterflies lay their eggs on the leaves and the larvae feed on the plants. Note that these plants contain cardiac glycosides, chemicals, that are toxic when eaten and make the Monarch Butterflies also toxic to any would be predators.
