Asclepias tuberosa L., Sp. Pl. 217 1753. (Syn: Acerates decumbens Decne.; Acerates decumbens var. erecta Durand; Asclepias decumbens L.; Asclepias elliptica Raf.; Asclepias lutea Raf. [Illegitimate]; Asclepias revoluta Raf.; Asclepias rolfsii Britton ex Vail; Asclepias tuberosa f. bicolor Standl. ......); It is a perennial plant growing to 0.3–1 metre (10 in–3 ft 3 in) tall, with clustered orange or yellow flowers from early summer to early fall. The leaves are spirally arranged, lanceolate, 5–12 cm long, and 2–3 cm broad. This plant favors dry, sand or gravel soil, but has also been reported on stream margins. It requires full sun. It is commonly known as Butterfly Weed because of the butterflies that are attracted to the plant by its color and its copious production of nectar. It is also the larval food plant of the Queen and Monarch butterflies. Hummingbirds, bees and other insects are also attracted.[2] Extracts were used by Native Americans as an expectorant for wet coughs and other pulmonary ailments.[citation needed] Use of the herb is contraindicated in pregnancy, during lactation or with infants due to the small amount of cardiac glycosides.[3] The plant looks similar to the Lanceolate Milkweed (Asclepias lanceolata), but is uniquely identified by the larger number of flowers, and the hairy stems that are not milky when broken. It is most commonly found in fields with dry soil. (From Wikipedia on 23.9.13)
