Please help me identify this tree. It has small berries that look like tiny mangoes. They ripen from yellow-green to red. The tree is currently about 15' tall. Smooth bark. Thank you.
This looks like a cranberry viburnum. The opposite placement of the leaves, the leaf shape, and the early fruit production all suggest this id. This is a wonderful native plant. Here is more about it: https://extension.umaine.edu/cranberries/highbush-cranberry/
There is also a European cranberry viburnum.
