Butterfly milkweed (Asclepias tuberosa)
Click on terms for botanical definitions.
Butterfly milkweed is a perennial that produces large, showy clusters of bright orange to reddish flowers. Petals are distinctly downturned. Stems are rough to hairy, and leaves are narrowly lanceolate, and oppositely arranged. Asclepias tuberosa is an exception to the Asclepias genus in that its stem does not contain the milky latex that distinguishes the rest of the genus and gives it the common name “milkweed.”
Butterfly milkweed flowers from spring through fall. It occurs naturally in sandhills, pine flatwoods, and other sandy uplands as well as along sunny roadsides. It is the larval food plant of monarch and queen butterflies. It also attracts hummingbirds, bees and other pollinators.
Butterfly milkweed is sometimes referred to as pleurisy root because Native Americans chewed the root of the plant to treat pleurisy. Today, it is commercially available as an extract and as a dried root powder.
