Poke milkweed, Asclepias exaltata

Poke milkweed is a milkweed for the shade! It grows between 50 cm and 1.50 m tall and has elegant, white, drooping flowers. It is not aggressive- only common milkweed is- and, therefore, is suitable for small spaces.
 
Ecology:
It is the host plant for the monarch butterfly and some moth species. Bees and butterflies visit it for its nectar. Pollen is in sticky pollen sacs that attach to insect legs. 
Rabbits will feed on its leaves.
 
Growing Conditions:
It prefers rich, moist, well-drained woodland soil in dappled shade. To increase fertility and organic matter in your garden, leave the leaves and chop and drop what you prune to have organic matter decompose in place.
Transplanting from pots into the soil often stresses this plant, and it can go dormant. Adequate water and shade help with the transition.
