Heirloom tomatoes are a type of tomato that is grown from seeds that have been passed down through generations, often for over 50 years. These tomatoes are valued for their rich flavors, unique colors, and diverse shapes. Unlike commercial varieties, heirloom tomatoes are typically open-pollinated, meaning they can reproduce naturally and maintain their characteristics. These tomatoes come in various types, including Brandywine, Cherokee Purple, and Green Zebra. They are often grown in home gardens and farmers' markets, where their taste and quality are prioritized over uniformity and shelf life. Heirloom tomatoes are celebrated for their contribution to biodiversity and culinary enjoyment.
