There are hundreds of wonderful seed catalogs out there. I have listed just a few of note because either they carry a particular variety listed in Greenhouse Gardener’s Companion or they are just good catalogs or web sites to check out. I’m sure many other catalogs offer quality seeds suitable for greenhouses, but this list is a good start. Mailing and web-site addresses are subject to changes over time. Some companies may charge for their catalog.
If you have any feedback on these listed companies (good or bad)- pass it on to us!
