Leela,
Hey! I live here in Gainesville. I have grown shiitakes and learned a lot,
Art Shiver of Southeast Mushroom is an excellent source of information. He's also an excellent source of fruit
trees at the Alachua County Farmers Market on 441. So is Pete Wallace at the same market. If you're looking for other food-producing perennials, check out the Edible Plant
Project. I also work at the 441 Farmers Market so if you're ever over there on a Saturday morning come say hi. If you're looking for plants, this is the season!
There is an excellent
local gardening group on
facebook that's mostly organic and very permaculture-friendly. If you're interested it's called Grow Gainesville.
Good to meet new
permaculture geeks in the area!
