This is Asclepias tuberosa, also known as Butterfly Milkweed, Butterfly Weed, and Pleurisy Root. Unlike many of the other milkweeds, this one prefers a dryer soil and must be planted in full sun. Another major difference between this plant and other milkweed is that this one does not have a milky sap. The orange and yellow blooms are out from mid Summer to early Fall. This milkweed attracts all kinds of wildlife, bringing in several different birds, bees, and butterflies. The hummingbirds are especially interested in this plant. This Plant is a Host Plant for the Monarch and the Queen butterflies. In places where there is no oleander Asclepias tuberosa is used as a larval host by the Polka-Dot Wasp Moth.
