  • Swamp Milkweed (Asclepias incarnata) is a showier variety of Common Milkweed. It is extremely elegant, producing willowy foliage and pink blooms. It will also attract beautiful butterflies and hummingbirds to your garden or meadow. Perennial.
  • Monarch populations have been in decline for a number of years, and the loss of nectar sources and milkweeds has been indicated as a major contributor to these declines.  This mixture is composed of native wildflowers, garden flowers and milkweeds which supply nectar sources for adult monarchs.  Milkweeds are utilized for egg-laying and provide food to monarch caterpillars. 
  • Named Butterfly Weed for a reason, this attractive and fragrant perennial will draw butterflies (and bees, and birds!) to your garden like a magnet! Impossibly attractive to pollinators, it almost doesn't matter that Carmine Butterfly Milkweed offers lovely purple/pink blooms from summer through early fall.
