Taking a stab at it as well. My best guess is viburnum. If you can post a picture of just the leaves w/some new growth that'd be helpful, too. I have viburnum
burkwoodii. In my
zone it's just finished blooming. Stays evergreen and w/o pruning, it can grow as big as forsythias. Tiny tubular
flowers seem identical to yours in addition to the slightly serrated leaves. It does smell wonderful also. To me (and everybody's senses are different) it smells kind of like bubble gum.
Right now it's home to a nest of cardinals. :wink:
