In no particular order of preference here are several seed companies that send me catalogs:
Park Seed Company
Territorial Seed Company
Vermont Bean Seed Company
Seed Savers Exchange
Richard Owen Nursery, Exciting Gardens
Burgess Seed & Plant Co.
Farmer Seed and Nursery
Jung Seeds & Plants
And a few I want but haven’t gotten in 2013 yet:
Note* I don’t receive anything extra from any of the companies listed above. I wouldn’t mind if they chose to do so but I don’t promote one over the other. Some folks have plants that do better in some areas than others. I would suggest trying to go with the folks in an area that has growing conditions that are similar to your own. Lots of times I use my seed catalogs as my window shopping. I look there to plan and get ideas and then I go with what I have and/or can find locally. I do tend to order specialty items from the catalogs as they can offer a lot more variety.
