I start requesting seed catalogs in the fall, so that by the time January rolls around I have a nice little pile to dig through.
This is a small and by no means comprehensive selection of (mostly) free seed catalogs I like and in most cases have ordered from and will continue to order from. I am not affiliated with any of these, and receive no compensation for providing these links. I will continue to update this with more seed catalogs over time.
Baker Creek Heirloom Seeds has an absolutely beautiful, glorious, glossy catalog, great selection, and great prices. I buy most of my seeds here.
Pinetree Garden Seeds. Besides the vegetable seeds, they also have a nice selection of spices, mushroom kits, and even soap making supplies.
Seed Savers Exchange offers a selection from the 25,000+ rare and heirloom seeds in their seed-bank. Members get access to an enormous variety of seeds not available in their catalog.
SeedsNow is a great resource for trying out varieties when you don’t need a full pack of a zillion seeds: they offer a choice of either full size packs or 99 cent sampler packs containing anywhere from 10 to 50 seeds, depending on the variety.
Seeds of Change offers certified organic and non-GMO seeds and food products.
Territorial Seed. Besides a catalog with a great selection, this site also offers tutorial videos and downloadable seed planting charts and growing guides.
Dave’s Garden Watchdog is a free directory of mail order gardening companies where gardeners can share their opinions on which companies really deliver on quality, price and service. Links are provided to the companies online stores. The site also indicates whether the companies offer a print catalog.
