Hi Nancy - the Raulston Arboretum had one years ago. I don't think it is still there today but it was maybe 10 feet tall when I saw it so it had to survive for many years to get that big. I remember they had a sign on it warning folks not to harvest the fruit because it was part of a research project. I don't remember a named cultivar but I think it came from Russia.

I plan to try them here. I doubt I will plant many - a little quince goes a long way for me. I read that some of them are sweet enough to eat like an apple.
