This plant is commonly called Rose Milkweed, though this rare flower is a white form!

Asclepias incarnata, rose milkweed, swamp milkweed, rose milkflower, swamp silkweed, or Indian hemp, is a herbaceous perennial plant species native to North America. It grows in damp to wet soils and also is cultivated as a garden plant for its flowers, which attract butterflies and other pollinators with nectar.

It is an upright plant, 100 to 150 cm (39 to 59 in) tall. The plants bloom in early to mid-summer, producing small, white-colored flowers in rounded umbels.

Swamp milkweed prefers moisture retentive to damp soils in full sun to partial and typically, is found growing wild near the edges of ponds, lakes, streams, and low areas-or along ditches. It is one of the best attractors of the monarch butterfly, which feeds on the flowers and lays her eggs on the plants. The emerging caterpillars feed on the leaves.

The plants are also sold as freshly cut flowers, mostly for their long-lasting flower display, but sometimes, for the distinctive seed pods.
