From the DuPage Wild Ones:

The annual seed-swap held at Warren Tavern is a popular event with our members and friends.  Seeds of many natives have been ripening over the past weeks and months, and our members have been busy collecting and packaging them.  We hope many of you have, too.  Bring your seeds and trade for something you don’t have.  If you don’t have seeds to bring, your are welcome to take some for a small donation.  We want you to start growing natives!  Last year we had over 100 species of native seeds available.

We will have items for auction and a raffle, so be sure to check out the bid sheets in the refreshment area and buy some raffle tickets!
