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.[1] It is widely cultivated in other regions, and is naturalized in California and in the southeastern United States from Texas to Virginia.[2]
It is an evergreen shrub or small tree growing to 2–5 m (rarely 6 m) tall, with smooth, pale grey-brown bark on the stems. The leaves are opposite, 5–10 cm long and 2–5 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...
