I thought this would be interesting to see where the hybridizing really started. Looks like 2013 was a banner year for hybridizers introducing their seedlings.
And it looks like the middle 1930's was when either there was more gardeners doing hybridizing or a few gardeners hybridizing and introducing a lot more seedlings.
