The fruit are small and are identical to cherries in shape and size. They are much smaller than the crabapple in my yard and this tree usually blossoms a week or more sooner than the crabapple. The reason why I wasnt sure if they were cherries is because the are hard and tart.
That being said Im not ruling out a species of crabapple I havent seen before, but would like to get a few opinions and go with the majority
