My neighbor has some trees...they are not identical. One has leaves shaped more like a fruit tree while the other has a more oval shape. Both produced similar, maybe identical looking small bell shaped flowers, similar to lily of the valley. We do not have pictures as the flowers have dropped. The flowers were ivory and the trees did not produce a nut or berry. Any ideas on what this might be?
A photograph of the tree, even minus flowers, would be a help cromba as it will make it easier for us to ID for you.
Photos of the leaves will be more helpful than the blossoms. Leaves are pretty distinctive between trees but the blossoms sometimes are very similar.
