Asclepias tuberosa, the butterfly weed, is a species of milkweed native to eastern North America. 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, as well as the dogbane tiger moth, milkweed tussock moth, and the unexpected cycnia. Hummingbirds, bees, and other insects are also attracted.
This plant is present in at least 44 states/provinces in this country.
It is a perennial plant growing to 0.3–1 meter tall, with clustered orange or yellow flowers from early summer to early autumn. The leaves are spirally arranged, lanceolate, 5–12 cm long, and 2–3 cm broad.
Some wild plants have been reported to have orange flowers that are very reddish.
Asclepias tuberosa blooms continuously throughout summer.
Sown outdoors after frost, a plant will flower and produce seed in the third year.
