It's been blooming for a month. Maybe more. Freeze and snow didn't phase it. I don't know what it is.
This shrub came with the house. I haven't figured out what it is. Maybe an evergreen cultivar of viburnum. Or not.
My friend Joan identified this shrub for me, almost immediately. It's a definite match: Viburnum tinus
Must be rugged and vigorous, given these pics, and the neglect it's doubtless had. Blooms Oct to June. Evergreen.
