Molly,
I plan on wintersowing seeds soon and if all come up as I hope, I'll have extras if you want to trade. What are you looking for and/or have you thought of doing a little winter sowing? Check my page and pick up my email address and email me directly (not thru Gardenweb) as I've heard that the email system here is questionable.
I also have Rose of Sharon Seedlings that seed themselves that I'm more than willing to send for trade or postage come spring if you're interested.
