What is an heirloom seed?

An heirloom variety is one that has been passed down from generation to generation. Generally, the variety must have been around for at least 50 years. They are open-pollinated, which means they have been exposed to natural pollination methods like insects or winds. They aren’t hybrids or genetically modified.
