HERITAGE Tomatoes are a special type of heirloom tomato that have been passed down for generations. These tomatoes are open-pollinated, which means they have not been crossbred with other varieties of tomatoes. This results in a tomato that is closer to its wild ancestor and has more genetic diversity. HERITAGE Tomatoes are available in many different colors, shapes, and sizes. They have a shorter shelf life than hybrid tomatoes and are less disease resistant, but their flavor is unmatched.
