Can someone identify this tree that I have growing at my home from these leaves and this "fruit"? The ground is covered with the green, plum like orbs but they are rock hard. The tree itself is at least 30 feet tall and recently was damaged by a falling branch during a storm.
We live in the state of Virginia in the USA. We live in the middle of five acres of all kinds of trees so getting the age of the tree will be hard but we have lived here for forty years so at least that old.
It is currently summer here, temps in the 80s & 90s. The storm dislodged the "fruit" and in the winter we find hard, dark brown nuts of some type beneath these trees. I'll try to get a photo of the whole tree tomorrow.
