Asclepias speciosa (Showy Milkweed) is an erect, clump-forming perennial prized for its brilliant spherical clusters of fragrant, pinkish-white, starry flowers, which bloom from late spring to early summer. Flowers are a great source of nectar for butterflies, hummingbirds, bees, and other beneficial insects. The flowers occur on stalks from the leaf axils and at the top of upright stems clad with velvety, large, oval, blue-green leaves. They give way to prominent seed pods in the fall, which look great in dried flower arrangements. When the seed pods open, they reveal seeds with long, silvery-white, silky hairs. A great choice for the flower garden and for natural settings. Milkweed plants are critical to monarch butterflies‘ survival, whose population in North America has plummeted by 90% in the last 20 years. By planting milkweed in your own garden, you can help reverse the fortune of these beautiful insects!
