Think Saltcedar is correct. The two in cultivation around here are C. americana (which produces an edible nut) and C. avellana. Neither one appear to have a red leaf margin.
Corylopsis pauciflora looks like a match. https://toptropicals.com/pics/garden/m1/EleNZ/Corylopsis_pauciflora072el.jpg
The flowers of Corylopsis pauciflora were featured in POTD in 2006. You wouldn't have identified the query here from that, though - apparently not a leaf in sight when it blooms in late winter.
Interesting. My first thought was Hamamelis. There are spent flowers visible in the close up. I think maybe they look like what would be found on Corylopsis.
Too coarse for C. pauciflora. The other more common one is C. spicata, but others are present here also.
My vote goes 100% to Corylopsis sp. At this time of year it will be easier to tell the difference between Corylus, Corylopsis and Hamamellis. Do please have another look at your shrub and add a good close up. Corylus will have well developed catkins by now. Hamamellis will have cluster of flower buds. Corylopsis will have enlarged flower buds ready to open next spring. Agree with Ron that it is not Corylopsis pauciflora. This is a much daintier, smaller leafed, lower growing shrub.
Buttercup winterhazel gets as tall as one shown and taller, but this takes many years. And its shoots are more numerous and more slender. Hazels do not have the same shoot and leaf structure.
