Here are some of my favorite seed sources, three catalogs(free on request from each company) and one on-line only seed company
Pinetree Garden Seed- They sell smaller quantities than most, at an equally smaller price. Great for someone just starting out and/or wanting to try a lot of different varieties.
Territorial Seed Company - They have lots of great varieties and good reference information and charts in their catalog and online.
Baker Creek Heirloom Seeds - This is one of the places to go, if you want open pollinated seeds and heirloom. Their catalog has beautiful pictures of diverse varieties. They do produce several different versions of their catalog, some that are sold on magazine racks, just to confuse everyone.
Renee's Garden Seeds - This is a delightful website with lots of interesting varieties and multi-variety packages. Her gardening help section is also very good.
These are just a few of my personal favorites, there are many more wonderful seed companies. Add your favorites to the comments.
