Thanks Arielle. I will look over the Willis and Stark bros. websites.After looking at a number of websites that well "fruit trees" I have noticed some definitely put a great deal into the descriptions and others skim the basics. So far WIllis has the greatest detail on all the berries and fruit. Not meaing you have to purchase from Willis, but just get the deeper description from them and apply it to a named fruit from another source.
Chokecherry is very tart. CHerries are usually listed as sour or sweet so that is easy. Beyond that I am useless.
I did a lot of reading on stark bros and thought they too had supper detail on the flavor of the berries. ANd noted if they could be eaten out of hte hand or needed to be cookwed with sugar. .
