Can anybody help identify this plant
This weed/plant/tree??? has grown to over 6-7ft in 2 months. Can anybody help identify it. I've got three of them growing out of nowhere in different spots over 30 feet away from each other with one in the shade of a big oak tree, another in a section of brush and this one next to the house. Leaves are as big as my hand and the "flowers" look like they might turn into berries but not sure yet as they are still small.
