How to Use Swamp Milkweed in the Landscape

Sticks and stones...these pretty blooming perennials shouldn't be considered weeds. Sure, they perform really well and can spread here and there in your yard.

After the flowers have faded, Swamp Milkweed forms eye-catching four-inch pods that are a favorite of young and old alike. Once ripe, they'll split to release the brown seeds...using silky white hair to catch the wind and reach new destinations.

Control their self-seeding spread by cutting off the pods before they split open. Dry them for gorgeous seasonal arrangements that last all winter long as an effective, charming method of size control.

Others encourage their growth and spend happy moments blowing their seeds to new parts of the yard. Your friends may beg you for some of the pods, too!

Wildcrafters and homesteaders can research an amazing variety of uses. In its various stages, Milkweed pods are used as a nematode insecticide, as an adhesive, and even as a poison ivy treatment.

Swamp Milkweed is an attractive, herbaceous perennial that would be perfect for those difficult, low spots in your yard, as it thrives in moist conditions. Use them in planned Rain Gardens to help filter potentially polluted water runoff from roofs and streets.

Of course, no Butterfly or Pollinator Garden would be complete without this host plant. Plant several in drifts through the center of your plantings.

Milkweed contains natural compounds like cardenolides, which protect the baby caterpillars from being eaten by birds. You'll love seeing the cute black, white and yellow caterpillars on your own plants!

If you grow your own food as part of an Edible Landscape, you'll definitely want to grow Swamp Milkweed. Tuck a stand near your Victory Garden to encourage pollinators to come explore your space.
