The story
Buttonbush grows with its feet in the water along ponds and slow streams across most of North America. Its flowers are perfect white spheres bristling with pins, like something a child would draw for a planet.
Planting
Full sun and wet soil: a rain garden, a pond edge, the low spot where the lawn mower gets stuck.
Growing
Never let it dry out. Cut it back hard in early spring if it gets leggy.
Harvest and use
One of the best butterfly and bee shrubs of midsummer. Ducks and other water birds eat the seed balls, and the thicket shelters nests.
What to watch for
It sulks in dry ground. Leaves come out late in spring; don't give up on it.
