Milkweed Near Me

We live in the United States. There’s a good chance, as a part of your everyday routine, that you pass around or through a green belt known as the "milkweed belt". But what is a "milkweed belt," and why are there so many around?Native milkweeds (Asclepias spp.) are essential for monarch butterfly (Danaus plexippus) caterpillars and support a diversity of pollinators with their abundant nectar. By including milkweeds in gardens, landscaping, wildlife habitat restoration projects, and native revegetation efforts, you can provide breeding habitat for monarchs as well as a valuable nectar source for butterflies, bees, and other beneficial insects. As part of our Project Milkweed, we have created this comprehensive national directory of milkweed seed vendors to help you find sources of seed. To learn more about monarch butterflies and how you can participate in conservation efforts, please visit the Xerces Society’s Monarch Butterfly Conservation page or the Monarch Joint Venture webpage.


We encourage you to only plant milkweed species that are native to your area. The Biota of North America Program’s (BONAP) web-based North American Plant Atlas provides county-level distribution information for all Asclepias species in the lower 48 states (milkweeds are not native to Alaska and Hawaii). Please refer to BONAP’s map color key for detailed information, and note that dark green indicates that the species is present within the state, while bright green shows that the species is documented to occur in that specific county. However, these maps do not convey the abundance of the species within each county.

Three Asclepias species have been introduced to the United States: tropical milkweed (A. curassavica), African milkweed (A. fruticosa), and swan or balloon plant (A. physocarpa). Of these, tropical milkweed (also called blood flower or scarlet milkweed) is the most widely available from commercial sources. However, there is preliminary evidence that where tropical milkweed has been introduced, its presence may cause monarchs to reproduce outside of their regular breeding season, disrupt monarchs’ migratory cycle, and increase transmission and virulence of the protozoan parasite (Ophryocystis elektroscirrha). Thus, some monarch scientists are concerned that the planting of tropical milkweed may lead to negative impacts on monarch health. For more information on this topic, please download this fact sheet by the Monarch Joint Venture or read this Q&A, also from the Monarch Joint Venture, about research related to tropical milkweed and monarch parasites.
