Swamp Milkweed is native to Southern Ontario and is a great wetland plant for the edges of ponds or for the garden. Excellent habitat plant for Monarch Butterflies. Fragrant pink-crimson flowers appear on its miniature tree-like form and sturdy trunk from early sowings. Requires full sun and does best in sandy soils.

Naturally stratify seed by sowing direct outdoors in Fall in a sunny and wet soil site. Indoor sowing requires a soil-less medium in February/March. Place seed in cold area for 3 months to stratify seed. Bring out after stratification and keep at 20°C (70°F) for 20-28 days for germination period. Barely cover seed, as diffuse light aids in germination. Indoor sowing in Spring results in late summer flowering the following year. Seeds from mature plants are easily dispersed by wind.
