I grow chocolate mint, also, and dry it for winter time because I drink hot tea all winter long. I've also made tea from strawberry leaves and rose hips. I dig dandelion in the fall and make dandelion "coffee," but only started that the last couple of years and this year I got really hooked on it. Traditional Medicinals has it commercially,so I bought some to tide me over, but I'll be digging a lot more this year because it's free in my backyard.
I also grow chamomile, but never get a big crop, and always wanted to grow echinacea, but it never did well here.
