Asclepias tuberosa - Butterflyweed

  • Butterflyweed is perhaps the showiest of the milkweeds (Asclepias spp.) because of the long-lasting and colorful flowers. This species is also unusual for a milkweed because its foliage lacks a milky latex. Because of the absence of milky latex, it is often referred to as Butterfly Weed, rather than Butterfly Milkweed.
