Description
The flowers are very showy and good for attracting butterflies. The plants tend to reach 2 to 4 feet (.60 to 1.2 m.) in height. Swamp milkweed plants can be distinguished from their other milkweed cousins both by these showy pink flowers and by their habitat, as they are the only species of milkweed that prefer to grow in wet conditions.
Swamp milkweed, as the name suggests, grows best in moist, wetland areas. It likes wet, clay soil, but it also prefers full sun. The plant is hardy in USDA zones 3 through 6, where it grows as a perennial. The plants spread naturally by wind-borne seeds and by creeping roots that spread out slowly under the ground.
