I am not so sure about the hardiness of Stanley, as I had one and it died.
I can't guarantee it's the cold that killed it however. But my feeling is
that Mont-Royal is quite hardier. Your memory is right about the genealogy
of Stanley - Grand Duke is an old English plum mainly used for cooking - is
it grown in Ontario?
