I said it was a guess and I could be wrong, but:
Ligustrum japonicum (Japanese privet ; Japanese: ãƒã‚ºãƒŸãƒ¢ãƒ) is a species of Ligustrum (privet) native to central and southern Japan (HonshÅ«, Shikoku, KyÅ«shÅ«, Okinawa) and Korea. It is widely cultivated in other regions, and is naturalized in California and in the southeastern United States from Texas to Virginia.
It is an evergreen shrub or small tree growing to 2â€“5 m (rarely 6 m) tall, with smooth, pale grey-brown bark on the stems. The leaves are opposite, 5â€“10 cm long and 2â€“5 cm broad, glossy dark green above, paler glaucous to yellowish green below*, thick and leathery textured, and with an entire margin
*some people say almost white
naturalized means spreading on its own and in fact it has become quite invasive in many areas.
Privet is still my best guess...
