Asclepias syriaca is a large, coarse, weedy plant with large, broad, oblong leaves. It forms round clusters of pale pink, fragrant blooms in the upper leaf axils. Also referred to as Common Milkweed, this perennial's leaves and stems exude a milky sap when cut. This plant is great for large meadows or larger gardens as it spreads rapidly via long (6'+) deep rhizomes. Common Milkweed is native to the eastern two thirds of North America. Its large seed pods split open in the fall releasing papery seeds on silky parachutes. Asclepias syrica's large leaves make it a preferred larval food for Monarch butterflies. This perennial is also a good nectar source.
