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.
Please use the drop-down menus below to search for seed sources by species and/or state. You can also review the map to ensure you aren't missing out on any vendors just across a state line from you! Below the search function, you can read more about finding and selecting the milkweed seed that is right for your area.
