If it's not a Chicago Hardy, maybe you could name it Ohio Hardy! You may be right, it may be a known variety, but some times there are beneficial mutations that occur within a particular cultivar. For instance: I have a friend with some commercial orchards. One of the varieties he grows is Gala. One day one of the workwrs shows up munching a couple of apples. It was something like 3 full weeks early (3 weeks is a big deal). So he takes my buddy over to where he got them and there is one branch on one tree in a pretty huge orchard with fully ripe apples on it! Long story short -- he's getting a million bucks a year on royalties for a new sub cultivar that ripens... you guessed it, 3 weeks early! So, even if it is a 'known' cultivar, who knows, it might have cold hardiness that exceeds the parent cultivar. I know there is no list, but who doesn't want a cold-hardy fig!!! Count me in!
