Asclepias incarnata
[3][4] It grows in damp through wet soils and also is cultivated as a garden plant for its flowers, which attract butterflies and other pollinators with nectar.Swamp milkweed is an upright, 100 to 150 cm (39 to 59 in) tall plant, growing from thick, fleshy, white roots.[6] The plants bloom in early through mid-summer, producing small, fragrant, pink to mauve (sometimes white) colored flowers in rounded umbellate racemes.They then release light or dark brown flat seeds that are attached to silver-white, silky hairs which catch the wind.[10] Swamp milkweed prefers neutral to slightly acidic soil with rich, wet, very muddy to average garden moisture and full sun or partial shade.It is most often found on the margins of flooded plains, lakes, ponds, waterways, marshes, swamps, and other wet areas.
