Check out Annie's Swaps in NH in the spring. It is a bit of a drive, but it is definately worth it. They've been going on for several years now and there are many swappers. We bring food and drink and swap plants. Keep on eye out for it. There's a thread showing past swaps so you know when to look for it... You can even email her.

Hi Debra

Thanks for reminding me. It is getting near the time for our fall plant swap. Not sure but think it will be Sunday Sept 29th.

Annie

I would love to trade for the first three items on your trade list.
What are you looking for? I have holly hocks, all sorts of echinacea from my garden and loads of commercial seeds because when they go on sale I go crazy and stack up on them
I also have several beautiful plants that I do not know their names Go on Face book and look at my pictures.
Hope to hear from you soon.
