I think it would take some genetic work to decide what Jubileum is. From
what I have read these are recent cultivar selections from various parts of
Hungary. The fruit at least makes it appear to have a lot of P. avium in it
so maybe it is comparable do a Duke cherry. I have never supposed that
Dukes would be even close to hardy here. The Jubileum looks mostly like
P. cerasus and that is how it is usually listed.
