I'm not sure but it looks rather like a privet in flower .

How big are the leaves and flowers?

That was my thought too!

Mine as well!

Agree :-)

It looks like the same as my ligustrum privet, if so more the merrier and the bees will thank you for it. ;-)

Thanks for the responses.
Achorman : the leaves are about 2" long x 3/4" wide.
Flowers are 4 to 6" in length.

That sounds about right for it to be a well grown privet Derek
