Easy care, drought tolerant, and deer resistant, Asclepias tuberosa ‘Hello Yellow’ (Butterfly Weed) is a bushy perennial prized for its brilliant clusters of bright golden yellow flowers that bloom continuously from early to late summer. Sitting atop upright flowering stems, clad with stiff, lance-shaped leaves, the colorful umbels are followed by attractive seed pods in the fall. When the seed pods open, they reveal seeds with long, silvery-white, silky hairs that look great in dried flower arrangements. The abundant foliage provides a dark-green backdrop that nicely compliments the cheerful flat umbel flowers. 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!
