Native to the Eastern and Southern parts of the US, Butterfly Milkweed (Asclepias tuberosa) is a showy and easy-going perennial that no garden should be without. The butterflies that flock to the fabulous clusters of nectar-filled, hot-orange blooms add to the fantastic summer show you'll get from this proudly American plant. Mass them for an unbeatable display or dot them around in your prairie-style garden meadow of flowers as an accent. Try picking the stems with their interesting seed pods as a creative addition to dried flower arrangements. You don't need to give these beauties any special care - they tolerate everything from drought and poor soil to chilly winters.
