Weird fruit from the tree

Here I show you a tree with a very exquisite fruit But what is unusual, some know it and others do not, this fruit is like a purple grape what can be eaten is a little like sweet and on this tree it was loaded and it almost has no top many of the fruits have fallen.

whenever I go near my work I find this plant I collected seed from it to plant in my garden to see if I get shade from the tree and can eat this fruit too
