Unlike the single-season hybrid seeds sold at most garden stores, open-pollinated seeds allow you to save seeds from the mature plants for the following spring’s harvest. Every farmer should want to save seeds from each successive harvest in order to replant stronger and better adapted seeds, and open pollinated seeds are the only answer. Dozens of companies, part of a blossoming heritage seed movement now specialize in heirloom and open-pollinated seeds. The following online catalogs provide both a variety of seeds and a bounty of information for the savvy self-educated urban-gardener.
