About Asclepias exaltata L.
Asclepias exaltata, commonly known as poke milkweed or tall milkweed, is a flowering plant species belonging to the dogbane family, native to eastern North America. Its green and white flowers bloom from late spring to early summer. When growing in moist shaded conditions, this plant can produce very large leaves. It resembles common milkweed (Asclepias syriaca, abbreviated A. syriaca), and can hybridize with this species when the two grow in close proximity. Poke milkweed occurs in moist woodland habitats, shores, and woodland edges. It grows in moist soil in locations that are sunny or partly shaded. It usually reaches a height of 2 to 6 feet (0.6 to 1.8 meters), but can grow taller than 6 feet when grown under favorable conditions.
