I have this growing, the picture is horrible but my camera keeps fogging up. I don't know what it is, probably something invasive.
is it a younger Chinese privet or some kind of privet?
Looks almost like sweetspire (itea) I can't tell by the picture how large the leaves are. Can you give us an idea?
Could also be ceanothus
Chinese privet, Ligustrum sinense, is blooming now in the eastern US. Horribly invasive. That is what it is.
