Common Milkweed

Asclepias syriaca
 
 
 
Probably the most important species to sustain the Monarch Butterfly. This aggressive, broad-leaved plant spreads by runners and is not recommended for smaller garden borders and display beds. The plant has a bold, chunky texture with stout, hairy stems which contain a milky white sap. In mid summer pink, spherical clusters of fragrant pink flowers appear which attracts many species of pollinators, including the Monarch. Large seed pods are produced in the fall and the seeds are wind dispersed by silks.  Not as widespread in the landscape in recent years due to current agricultural practices and herbicide use.
