Asclepias tuberosa

Butterfly Weed
Perennials, Flowers


Milkweeds (so named for their milky sap) are the best-known representatives of this group of plants. Bloom in summer, typically bearing many small, starlike flowers in broad, flattened clusters at branch tips. All have inflated seedpods with silky seeds. Just a few species are cultivated in gardens.

Asclepias tuberosa

Native to eastern U.S. From a perennial root, many herbaceous stems rise every year to form a clump about 3 ft. tall, 1 ft.wide. Clusters of bright orange flowers attract swarms of butterflies. All types make long-lasting cut flowers. Provide good drainage.

Gay Butterflies strain features yellow, red, orange, pink, or bicolored blossoms; ‘Hello Yellow’ has bright yellow blooms.
