White swamp milkweed (Asclepias perennis) is an herbaceous perennial (height – 12 to 18 inches) for full to part sun. This beautiful, native wildflower is naturally found on floodplains, water way margins, marshes, cypress swamps, ditches and wet lands. Although it does thrive with regular moisture, it will also tolerate most garden situations including somewhat well-drained soils. It propagates by seed and tolerates temperatures to zero degrees Fahrenheit. Asclepias perennis blooms from May to September. Its pinkish white flowers attract butterflies and other pollinators, and its foliage is larval food for both the Monarch and Queen butterflies.

At Native Nurseries, we typically stock white swamp milkweed in quarts and 1-gallon pots. Currently we have 1-gallon pots only. As always, give us a call to check availability before making a special trip (although we’re always happy to see you). Sorry . . . we do not ship plants.
