I owe this shrub an apology. For nearly two weeks I've been referring to it by the wrong name: Daphne. Worse, I had titled & tagged my Flickr images incorrectly. Ack. So embarrassing.
Perhaps the safest action would be to identify this as "deciduous shrub with pink flowers that blooms in February" so that I won't make a second taxonomic blunder. But yesterday & today I consulted several references (1, 2, 3, 4) and the flowers' structure & bloom time are consistent with the images & descriptions of Viburnum x bodnantense 'Dawn.' So I'm going to tentatively identify it as this.
This particular Viburnum is too large to grow on a balcony. These are photos of shrubs blooming in late January/early February throughout my neighbourhood.
I think Viburnum x bodnantense 'Dawn' would make a lovely companion for winter-flowering Hamamelis (witch hazel). If I had a large enough space & the right conditions, I'd grow one of each, to add pink & yellow to grey, late-winter days.
