Aquatic Milkweed (Asclepias perennis)
Description
Stem is a dark purplish-green color in contrast to the evergreen color of the leaves. Stands erect to ascending. Leaf arrangement is opposite. Leaf attachment is petiolate with short petioles approximately 2/3 in (1 1/2 cm) long. 3+/- umbels to a stem (Webref 20). This species can be easily identified before the flowers open because the tips of the corollas are pink creating a large pink spot at the apex of an unopened flower. Leaves are relatively short and narrow. Grows in areas with soils that are continuously wet (Webref 20).
