Actually I have three cherry trees. These two tart cherries, and I have a Stella, which is a sweet dark cherry, much like the Bing. It's cherries were ripe about two weeks before the tart cherries, and I didn't get a picture of them. I don't always get a harvest on the Stella, as it blooms early and sometimes catches a frost which greatly reduces it's productivity. I would think you could grow the sweet cherries in your zone. Not sure about the tart cherries. I don't know how long a chill period they need.
