Looks like it to me.. In zone 9 coastal California it always blooms at Christmas and perfumes a large area of the garden.

Yes that certainly looks like wintersweet.

Chimonanthus Praecox .....I do hope that you took time to smell the flowers.

Oh, yes, ahhh! Mine bloomed through January, it lasted a long time this year. Still blooming in fact.

@Silversurfer: I did not think to, given they were sodden wet. But, I did make a point of catching Edgeworthia Chrysantha during this vital month.

I went back yesterday and close enough the two both had that honeysuckle scent to them.

Next thing to do is go back when it has leaves and feel them.
Unlike many leaves they are rough to the touch.
Seed capsules are interesting.
