"Long before that, the Heirloom Seed Project at Landis Valley Farm Museum was working to preserve old varieties. The project began in 1985, making it one of the earliest in the country, and at Landis Valley, the focus is narrow."
"All the plants that grow in the Heirloom Seed Project's gardens are varieties the Pennsylvania Germans grew from 1750 to 1940. Many of those varieties have names with a distinct Lancaster County sound, such as Amish paste tomato, Grandma Hershey's sugar peas, Pennsylvania German red lima beans, and Lancaster sure crop corn."
