This plant was already at our house when we bought it. It was fairly small - maybe 2'x2'. Since the two years we've been here it's maybe doubled in size. Blooms in our zone 6 about mid-May. So pretty and delicate! White arching branches that bob in the wind. I love mine, but worry it will take over that side of the yard - I've seen them in my area get HUGE. I'll have to figure out how to prune....

This cultivar is a hybrid between Spirea trilobata and S. trichocarpa. The plants form a mound of arching branches to 5 feet with numerous white flowers in late spring-early summer. Like many spirea, it is a rather coarse shrub after blooming.
