Also need help identifying this plant. Think it is common, but still can't find it. Leaves are leathery. Many of the deep green leaves have changed to orange-red during the winter. Blooming now with clusters of small bell shaped flowers. Plant is very hardy.
At first I thought escallonia as well, but after looking at a bunch of white ones, they didn't seem right. Flower clusters we at the end if the stem, larger clusters and in general they are made up of multiple petals, not a single seeming tube (like the picture) and all escallonias seem to have the anthers and stamens and such protruding from the flower. The ones in the photo don't appear to be visible.
The flowers did remind me very much of the pink dawn viburnum tho (viburnum bodnantense). So then checked up on oddball viburnums and there it was.
I think that there are quite a few winter blooming viburnums. I hate that I'm on the spot for these tender forms that I am only lucky enough to experience if I get to travel to a warmer climate zone.
My recent trip to snowy Seattle in December 2008 was one such opportunity. Weather precluded much interaction with plants, but I took every picture I could of shrubs that weren't under a foot of snow at the Washington Park Arboretum. I am not within e-reach of those images right now, so I can't lend a guess - but V. grandiflorum (one of the parents of 'Dawn') was one that was flowering then - but this is not that.
jmurt might provide some more images of how the leaves attach to the stems, bud/leaf scars from old stems, the trunks and main limbs, etc. If you have access to the plant and can take pictures, swamp us with them.
