heirloom plants

Old-variety garden specimens

Heirloom plants are varieties passed down through generations, typically open-pollinated rather than commercially hybridized.

The term implies age—usually varieties developed before industrial agriculture—and suggests distinctive flavor, appearance, or regional adaptation that mass-market breeding has sacrificed for uniformity and shelf life: heirloom tomatoes, heirloom beans.

Gardeners value them for genetic diversity and historical continuity.
