Butterfly Milkweed

Asclepias tuberosa

Perennial flower

The orange one. A dry-meadow milkweed with clusters of small vivid blooms that hold a huge diversity of pollinators through the hot months. Unlike most milkweeds, its sap is not white — a botanical curiosity that makes it easy to identify.

Notes on growing

Slow to establish from a deep taproot; plant it once and leave it alone. Emerges late in spring — mark its spot so you don't accidentally dig it up. Doesn't transplant well once mature.
