Asclepias tuberosa 'Hello Yellow'

Butterfly Weed

Asclepias tuberosa, or Butterfly Weed is native to much of the United States, very much at home in open meadows. old fields, roadsides, and sunny summer gardens. From early to midsummer butterfly weed produces very showy clusters of bright yellow-orange flowers that appear atop stems lined with green strap-like leaves.

'Hello Yellow' has lots of golden yellow flowers in July and was hybridized from the native Asclepias tuberosa.

A wide array of butterflies are attracted to butterfly weed. In fact, Monarch larvae and adults specifically rely on Asclepias tuberosa for food and defense. When their caterpillars eat the foliage they become distasteful to predators. Butterfly Weed is an important and beautiful addition to any sun garden!
