farmerdill said:No Mam; All "heirlooms" are OP. Some differentiate based on "heirlooms" either being introduced by amateur breeders or found by a family who has grown it for several generations as opposed to those OP's developed By main line sources like Livingston, Burpee,
USDA, Universities etc. Some quote age of introduction. There does not seem to be a universal accepted definite. A new introduction will be vended as an "heirloom" by some and denied by others.

Yes there are some modern day breeders introducing new open pollinated varieties. So not hybrids and will breed true but not heirlooms. But Open pollinated just as heirlooms are.
