Welcome to Monarch Watch's Milkweed Market!

Sullivant's Milkweed


Go directly to our new Milkweed Request Form or continue reading for additional information.

Monarch butterfly numbers have been at an all time low for the last two overwintering seasons, and many pollinators are declining as well. The widespread planting of herbicide tolerant crops, intensive farming, and the ethanol mandate has led to a rapid loss of habitat. 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.

In 2013, we distributed 21,000 plugs. In 2014 we had a bigger target, and sold or distributed over 59,000 plugs. Our goal for 2015 is to distribute 100,000 pesticide-free milkweed plants!

Our milkweed plugs come in unmixed flats of 32 plants. The plugs cost $66/flat, shipping included. Shipping is via UPS ground. We accept check or money order only, payable to Monarch Watch. Purchase orders are accepted in most cases. Your check WILL NOT be deposited until we know your plants can be shipped.

Use the map and table below to determine the plants we are supplying to your area. These plants are currently in the germination phase. This list is a prediction, and not a guarantee of availability.

If you wish to request milkweed, please go to monarchwatch.org/milkweed-request to access our new online milkweed request form. This form does not automatically generate an order. Each request must be reviewed so that the appropriate plants for your region are selected. We only ship plants to the ecoregion from which their seeds originated.

We are contracting with native plant nurseries to increase our impact nationwide. New in 2015! We are partnering with a Florida nursery to fill the gap in the Florida Panhandle, and they will be providing a warmer nursery for our Texas* species. We are also in the process of creating a partnership with a grower in Arizona to grow some of the unique desert southwest milkweed species.

All communications involving orders and shipping should be directed to Monarch Watch at milkweed@monarchwatch.org.  Or call 1-888-824-4464.

Thank you for your interest and support!

*TEXAS CUSTOMERS: Please note that our Texas species will not be available until late April or early May. We apologize for any inconvenience.

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.

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.
