Another two unknown trees to post from the orchard. These two don’t appear to have grafted sections. They also have such different leaves that I doubt they are fruit. Thoughts? Identifications?
Tree number 5
Tree 6 (actually two trees that are alike)
a middling life 
Not sure about number 5, but I’m pretty sure number 6 is a dogwood.
Not sure of number 5, but number 6 is a dogwood.
5 would be a purpleleaf plum– typically an ornamental but some do bear fruit. Number 6 is obviously some sort of dogwood. When it blooms it should be obvious what kind.
It’s a dogwood. Probably Cornus mas since you’ve got edibles. See http://www.fruit.cornell.edu/mfruit/cherries.html
