Asclepias tuberosa, commonly known as butterfly weed, is a species of milkweed native to eastern and southwestern North America.[3] 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.[4]

It is a perennial plant growing to 0.3–1 m (1–3+12 ft) tall. The leaves are spirally arranged, lanceolate, 3–12 cm (1+144+34 in) long,[5] and 2–3 cm (341+14 in) broad.
