Asclepias incarnataAlso known as:
Asclepias incarnata is a striking, medium-tall plant with narrow, elongated leaves on branching stems. It has large terminal clusters of fragrant, deep-pink flowers. In fall, the plant bears 5" long, brown seed pods that will remain into winter.
This milkweed is native to just about all of north America east of the Rockies. Although a swamp plant, it can be grown in low lying areas of a garden where the soil remains consistently moist. It is tolerant of a wide variety of soils from well drained to mucky, and even heavy clay. Excellent around water features in full sun. It may bloom as early as June in the southern part of its range, and as late as September in the north. Zones 3-10
Easy to propagate from seed. The tap roots prefer to remain undisturbed, however, mature plants may be divided in spring.
Long used for its medicinal value, all parts of the swamp milkweed may be toxic in large quantities. Both flowers and seeds are edible, as well as the plant and young shoots when cooked. It is a larval host for the monarch and queen butterflies. Susceptible to aphids. An underutilized plant ideal for wetlands.
