Live in zone 9 in USA. This shrub is about 6 feet tall and we have to trim it every year or else it'll grow taller and block windows. Planted 5+ years ago.
White flowers it looks like too. Would like to plant this in backyard too for privacy. House faces north. Backyard has 12 hours sunlight.
Edit: it looks more and more like waxy leaf ligustrum but it's been trimmed in to a rectangular shape.
