White swamp milkweed is a perennial plant in the Milkweed family (Asclepiadaceae). Milkweed flowers are highly specialized. The floral structure is comprised of a corona, five hoods each with one horn, and five reflexed petals. The hood is a petal-like structure that arises from the base of the filament and acts as a sheath around an inner appendage called the horn. White swamp milkweed produces an inflorescence with few flowers. Flowers bloom in mid-summer. Aquatic Milkweed is one of the few shade-tolerant milkweeds. This is an excellent choice for use as a Monarch host as it will remain evergreen in mild winters in zone 8B and warmer and is a good substitute for Tropical Milkweed for those looking for a reliable native perennial milkweed with a smaller compact habit. Asclepias perennis is native to much of the eastern central US. Provide a 4-6 hours of sun in average moist to semi-moist soil for optimum vigor and flowering. Plant the Aquatic or White Milkweed in spring until about midsummer in zones 6-8 to help ensure plants are well-established before winter. It can also be enjoyed as a container plant but it should be protected if there is a chance that the soil can freeze.This is one of the few native milkweed seeds that do not need to be cold-stratified. Does well planted in containers.
