I believe the answer would be: A. heirloom.

     A garden plant that has been passed down within a food family and is generally not commercially grown is called a/an heirloom product or heirloom variety. The heirloom product represents an old cultivar of a plant which is isolatedly grown and maintained by gardeners or ethnic minority communities.
