I purchased and planted a tissue-cultured ‘Bali’(Evans) cherry from St. Lawrence Nursery back around 1996. Planted 20 ft from a Montmorency. They are very different… I do not believe they are the same species, nor do I believe that Evans is a seedling of Montmorency.
While the photos I’ve seen posted by Konrad, and others in zone 4 and colder look fantastic… performance in zone 6 was pitiful. Evans is enough later than Montmorency that plum curculio &/or other insects hit the fruit hard long before ripening. I don’t think I ever got to eat a ‘perfect’ Evans cherry (there weren’t ANY), and after the first couple of years fruiting, I didn’t even bother to look at the thing, other than to say, “What a waste of space.”
Evans/Bali eventually started throwing up suckers up to 20-30 ft away… very distinctive leaf morphology. I dug some and shared with fellow NAFEXers, and I think I have finally eliminated the last of the suckers that persisted after the original tree declined and died.
I would advise against Evans/Bali if you’re in a warmer climate than zone 5… maybe even warmer than zone 4… up there in the real frigid northland, it looks like it’s hard to beat, but it’s a dog down here near the Z6-7 interface.
