Swamp Milkweed was in full bloom last week. I purchased 5 more plants this spring and added them to the rain garden by the driveway. All are doing fantastic, and providing an excellent source of nectar for pollinators.
Swamp Milkweed is a native perennial of wetland edges and moist soils. If you have drier soils, it can be short lived if there are periods of drought. But if you are fortunate to have a low lying area in full sun in your yard (that stays moist), swamp milkweed is an excellent candidate.
The light to dark pink flowers are extremely fragrant, reminding me of a vanilla scent. The leaves are opposite in arrangement, narrow and pointed.
Milkweeds have the most interesting flower form, comprised of horns and hoods, the whole cluster arranged in an umbel. Just take an up close look at the flowers some time to appreciate their form. Seed pods are upright and hold numerous seeds with silky hairs attached, the pods open and the seeds are wind dispersed.
I've had one plant in particular that the Yellow Faced Bees (Hylaeus spp.) have been coming to. Their small size allows them to dip their heads down into flowers for the nectar rewards.
Swamp Milkweed is native to central and eastern North America. See map for range.
