Put LeafSnap on your phone and it will tell you.
I have never noticed any berries, but this is the first year I noticed the small white flowers. I took the picture last week when we had all the rain. Shortly afterwards the ground beneath was covered with the flowers. It has been in my yard for over 30 years. I have not seen any other tree like this anywhere else near my home. But it does look a Farkleberry.According to PictureThis it's a Farkleberry, a species of blueberry that grows up to 23' tall. Does it get berries?
