Open pollinated means this plants flowers are fertilized by bees, moths, birds, bats, and even the wind or rain. The seed that forms produces the same plant the following year. 

All heirlooms are open pollinated, but not all open pollinated plants are heirlooms. Only a small fraction of the plant world is considered heirloom.

This variety has a history of being passed down within communities and families as early as the 1700's, similar to the generational sharing of items like jewelry or furniture.
