Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
Just guessing.
My first guess was Elderberry but looking at the darker colored older foliage (I am assuming it is all one plant) could it be some kind of Euonymous?
Sunset Zone 28, AHS Heat Zone 9, USDA zone 8b~"Leaf of Faith"
