Butterfly weed (Asclepias tuberosa, also called Canada root, Chigger flower, Chiggerflower, Fluxroot, Indian paintbrush, Indian posy, Orange milkweed, Orange Swallow-wort, Pleurisy root, Silky Swallow-wort, Tuber root, Yellow milkweed, White-root, Windroot) is a species of milkweed native to eastern North America. It is a perennial plant growing to 0.6-2 m (1 -2 feet) 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.

The common name comes from the butterflies that are attracted to the plant by its color and its copious production of nectar. Butterfly weed is also the larval food plant of the Queen butterfly.

Identification

The plant looks similar to the Lanceolate milkweed (Asclepias lanceolata), however the Butterfly weed is uniquely identified by the larger number of flowers and hairy stems that are not milky when broken. It is most commonly found in fields with dry soil. Template:Commons
