Mature Spread: 3–6 feet
Growth Rate: Moderate
Attracts Wildlife: Birds, pollinators and mammals
Messiness: Buttonbush drops its leaves in autumn. Fruit persists through winter and drops in early spring.

Preferred Soils: Prefers moist to wet, rich, high organic matter content soils. Can do well in clay, loam, shallow rocky, and/or sandy soils. Prefers acidic (<6.0pH) soils.

Pruning: Little to no pruning is required for buttonbushes unless they’re being shaped to preference. Any dead, broken, or diseased limbs should also be removed to help keep the shrub as healthy as possible.
