Far be it from us to tell you that you could not grow anything! You have more success than a lot of people in prime growing areas! Now, about your question: So far as we can tell Prunus avium 鈥楽tella鈥 is dwarf to semi-dwarf (height estimates range from 7 feet to about 15 feet), hardy in Canada to zone 5鈥攁lthough one US vendor says it’s hardy to US zone 4 (the north central area), so it might do ok in your area. Stella is also a 鈥渦niversal鈥 pollen source, bless her heart.
We are getting less information about Royal Ann (aka Napoleon): In the US it is hardy to zone 5 (鈥10 to 鈥20掳F) and/or it requires 700 chilling hours below 45掳F. Finally! Canadian nurser GreenBarnNursery says Napoleon is hardy to Zone 4 (鈥30掳C).
Every source suggests that both fruits are mouth-wateringly delicious. So it might be worth a try…! And if you get a crop, send us a few! ;-)
