Hello!
I've been collecting seeds for native plants and have a LOT to share. If there's any seeds that you're interested in, please send me a TreeMail and tell me which seeds and if you can pick up from Evanston, not too far from where the swap was. If you can't pick up, please tell me your mailing address. I don't get notified of updates to this thread, but I do get notified of TreeMails.
Please note that most of these seeds will require cold moist stratification. All of the seeds were collected from plants this year unless otherwise noted.
The majority of these seeds were collected by non-specialists, so there is the risk of misidentification.
