Buttonbush is best adapted to shorelines and swamps with saturated soil and full sunlight. It will tolerate water depths up to three feet. Flowering is poor in the shade or in dry soils but it will tolerate drought.
Pruning is usually not necessary, but may be done in early spring to shape. If plants become unmanageable, however, they may be cut back near to the ground in early spring to revitalize.
Naturalize in woodland areas, native plant gardens, pond margins, low spots or shrub borders. May also be grown in shallow water at the edge of ponds or large water gardens.
It has exceptional wildlife benefits. The seed is eaten by eight species of waterfowl and the twigs by three species of mammals.
