Common Milkweed is a perennial plant native to southern Canada and parts of the eastern US. It grows clonally, which means it sends up new shoots of itself. The shoots are edible, and compared to asparagus. Only the shoots of common milkweed are edible, the plant is otherwise toxic. Some have eaten the flower pods as well, but I have no experience with this, and cannot recommend it. They'll grow to be over 7 ft tall with broad, oval-shaped leaves. Flowers range from whitish to purplish, and are quite fragrant, attracting pollinators. All milkweeds are host plants to the Monarch Butterfly larvae.
