Answer: I have a few sources that may be of help to you. I think it's a great project! One thing to think about is that many of these seeds have long germination times, and some need chilling before they will sprout. (Think of how native plants might have adapted to your long winters.) You'll want to research each plant's needs so you'll know what to do and to expect.
