Contribute Your Seeds

We welcome collections of new seeds on an ongoing basis for use in future research.  To be useful, seeds must be:
1. Common milkweed seeds (Asclepias syriaca)
2. Collected from naturally occurring populations (not planted)
3. Submitted with the associated data. Please follow the directions in the protocols and be sure to submit data about the site from which you collect as well as the individual plants from which you collect.
October is often a good month for seed collection.
Thank you for contributing to our seed library!
