What are good places to get plants/seeds for herbs this time of year? I want to get a jump on next year's growing, and I need some obscure things that I just can't seem to find. French Tarragon, Lemon Balm (plants for those 2, as the lemon balm seeds are not growing for me), Calendula, etc. I have sources for the popular herbs, but I'm looking for stuff that most people don't use. I'm in Michigan, and I will have a greenhouse (arriving today!!!) to grow in for the winter. Your help is appreciated!
