If you can wend your way amid the ads, Garden Betty’s annotated list of her favorite catalogues will bring you beyond the basics. Her intro: “If you love to curl up with a seed catalog and devour it like a good book, this is my roundup of the best seed catalogs that I order from year after year for my vegetable, herb, and flower gardens. You’ll find heirloom seeds, certified organic seeds, open-pollinated seeds, and hybrid seeds bred for pest and disease resistance, as well as seed garlic, seed potatoes, onion sets, shallot sets, and asparagus crowns.“
