There's this lovely shrub near my pool, about 7 feet high. It has flowers in clusters, like hydrangeas or lilacs. They vary from pale pink to pale green. And though I chose a poor (slightly deformed?) example when I picked one for a picture, it definitely has 4 petals per flower, not 5. You can tell if you look closely. And many of the larger leaves had 5 lobes, if that helps. So far I've seen it blooming in June/July.
