Asclepias tuberosa – Butterflyweed

An herbaceous perennial that loves a hot dry site. It forms a clump growing two feet tall & wide. Bright orange flowers decorate the plant from June through August. Somewhat slow to start, although easy to grow, tuberous roots make it difficult to move after it’s established. If seed pods are not removed it may self-seed.

Flowers are a nectar source for many butterflies and the foliage is a food source for Monarch larva (caterpillars). This member of the Milkweed family does not have milky sap. A showy native wildflower good in mass plantings or scattered throughout a prairie or meadow. The bright orange umbelliferous blooms give way to prominent spindle shaped seedpods 3-6 inches long.

It works well with other native perennials such as Coreopsis, purple coneflowers (Echinacea purpurea), blazing star (Liatris spp.), black-eyed Susan (Rudbeckia fulgida), and grasses such as little Bluestem (Schizachyrium scoparium) or prairie dropseed (Sporobolus heterolepis).
