Heirloom plants are varieties of fruits, vegetables, and flowers that have been passed down through generations, often for 50 years or more. These plants are typically open-pollinated, meaning they can reproduce true to type, allowing gardeners to save seeds for future planting. Heirloom varieties are valued for their unique flavors, colors, and historical significance. Many heirloom plants have rich stories and cultural importance, often linked to specific regions or families. They are often grown in home gardens and community farms, promoting biodiversity and preserving genetic diversity in agriculture. Examples include Brandywine tomatoes and Cherokee Purple tomatoes, which are cherished for their taste and heritage.
