Swamp milkweed Interesting Notes

The leaves of the Red Milkweed are a preferred food source of Monarch caterpillars. Plant Red Milkweed and start your own butterfly farm! The bright pink and red flowers appear in June and July on five foot stems. Preferring moist soils, this is a great plant for naturalizing in roadside ditches, detention basins, and other wet soils that often dry out in summer. No butterfly garden is complete without Red Milkweed. Prairie Nursery

Asclepias incarnata Growing and Maintenance Tips

Swamp milkweed, true to its name, prefers consistently moist soil, but performs admirably in average, well-drained gardens as well. Full sun is best and some shade is tolerated, though blooming time and color may suffer.
