Welcome to Monarch Watch's Milkweed Market!

Sullivant's Milkweed


Monarch butterfly numbers are at an all time low and many pollinators are declining as well. The widespread planting of herbicide tolerant corn and soybean lines, intensive farming, and the ethanol mandate have led to a rapid loss of habitats for monarchs, and many species of bees and other pollinators. This loss of habitat threatens the monarch migration and all the species dependent on the services of pollinators to provide the fruits, nuts, seeds and foliage they feed on. Monarchs and pollinators need our help. By planting milkweeds, the host plants for monarch caterpillars, and nectar plants for adult monarchs and pollinators you can help maintain the monarch migration and sustain the pollinators whose pollinating services maintain our ecosystems.

Last year we commissioned the production of 25,000 milkweed plugs of some 15 species. It was a gamble (see monarchwatch.org/blog/2013/06/the-milkweed-gamble) but this program was wildly successful and we distributed 21 thousand of the plugs in late spring and later in the fall. We have a bigger target this season. We are presently overwintering 29 thousand milkweed plugs. These will be grown out for distribution early in the spring. We have started the production of another 30 thousand plugs for distribution in May and early June. Those not sold in the spring will be available for planting in September and October. Below you will find a list of states with the milkweed species available for each state. The numbers of plugs are robust for some species and low for others. So, if you are interested in some of the less common species, please plan on ordering soon.

The milkweed plugs come in flats of 32 and are generally 3-5 inches high at the time of delivery. The flats cost $66 each with shipping via UPS Ground Service included. The minimum order is one flat and an invoice will be mailed to you before the plants have shipped. Three flats can be shipped in one box. Please contact us about price breaks if you are ordering more than 6 flats.

If you would like to place a milkweed order, please email with your contact information (name, address, email, and phone number) and the number of flats you would like of each species.

Our mission is milkweed restoration and to that end we only ship plants to ecological regions from which the seeds were obtained. This project has been supported by a large number of volunteers who have supplied seeds of many milkweed species from most areas of the country. There are some gaps, the biggest being the Southeast where it has been difficult to obtain seeds. If we don't have milkweeds available for your area, please take advantage of the new vendor listing here in the Monarch Watch Milkweed Market (download vendor PDF file). More than 200 vendors that sell native milkweeds in various regions of the country are currently listed.

If you can't find milkweed for your area, but are interested in acquiring milkweed plants in the future, please email us at . This will help us to plan for our milkweed plug production goals next year. Since we are dedicated to returning milkweeds to areas from which the seed originated, we may ask you to help acquire seeds of milkweed for your area.

We are working with Applied Ecological Services, a restoration company that specializes in the production of native plants. They have produced excellent milkweed plugs for us for several years. The flats are shipped from their greenhouse in Baldwin, KS. Orders from California will be shipped from a nursery in that state. All communications involving orders and shipping should be directed to us here at Monarch Watch at .

In order to keep many species in the Milkweed Market available, we rely on local seed collections from across the country. We have created a Milkweed Regions & Seed Needs section of our Bring Back the Monarchs program. We really need your help to keep this program going! We welcome any questions, comments, or suggestions regarding the new Monarch Watch Milkweed Market. Please feel free to contact us anytime. Thank you for your interest and support!
