Description

Asclepias incarnata ssp. pulchra

Also known as:

swamp milkweed

,

Scientific Synonyms:

Asclepias incarnata var. neoscotica, Asclepias incarnata var. pulchra, Asclepias pulchra

Description

Asclepias incarnata ssp. pulchra, is similar in most ways to A. incarnata. It has a smaller native range and is concentrated in the east-coast lowlands. It can be distinguished from A. incarnata by its broader leaves, bushier appearance, and deeper bloom color (though it can be highly variable). It is a striking, medium-tall plant with 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.

Cultivation

Although typically a swamp plant, Asclepias incarnata ssp. pulchra 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 August in the north. Zones 4-9

Propagation

Easy to propagate from seed. The tap roots prefer to remain undisturbed, however, mature plants may be divided "carefully" in spring.

Additional Notes

It is a larval host for the monarch and queen butterflies. Susceptible to aphids. An underutilized plant ideal for wetlands.
