Understanding the difference between open pollinated, heirloom, hybrid, and genetically modified seeds is crucial to selecting the right seeds for your garden, whether you're planning to save your own seeds or just simply eat your garden's bounty.
Saving open pollinated seeds is the oldest way of seed saving. Open pollinated seeds are seeds that have been saved from a crop of open pollinated plants. This is done by keeping one variety of plants far enough away from another variety so that cross pollination does not occur. With open pollination, as long as pollen is not shared between different varieties, the seeds will be true to the parent plants and will hold their quality over time.
