Grow Buttonbush to Attract Butterflies and Pollinators
Updated on Jun. 14, 2022
Pollinators and Birds Love Buttonbush
Buttonbush’s fragrant white flowers are a favorite of bees, butterflies and other pollinators, and well-loved by gardeners. “This is one I think more people should be growing,” says Dan Scott, the former associate director of gardens and facilities at the American Horticultural Society. “Buttonbush presents an incredible white pincushion-esque flower in midsummer.”
Once it starts flowering, this long-blooming plant provides months and months of enjoyment for gardeners and pollinators alike.
Buttonbush’s white spheres are actually made up of tons of smaller flowers that pollinators love. You might see butterflies, hummingbirds and bees stop by the aromatic flowers. Pollinators rely on nectar from the white blooms and, in turn, these pollinators spread pollen from flower to flower.
As the flowers fade, spherical fruits appear and persist through winter, providing seeds for a variety of birds. Ducks and shorebirds are especially fond of the seeds and songbirds may take cover in the large shrub.

Host Plant for Butterflies
Buttonbush also supports several types of caterpillars as a host plant. A host plant is a tree, flower or shrub that caterpillars hatch on and eat.
These shrubs may attract garden moths like the hydrangea sphinx, titan sphinx or the royal walnut moth. You may spot the adults fluttering around the plants or the caterpillars on the leaves.

Where to Plant Buttonbush
Many plants need a spot with well-draining soil and plenty of sun, but not buttonbush. You do want to avoid planting it in a dry area.
In the wild, this plant grows in wetlands and lowlands. So pick a spot that is consistently damp and partly shaded. Be sure to give it room to grow—in the right conditions, it can spread up to 12 feet tall and wide.
For a smaller-space option, consider Fiber Optics buttonbush. Smaller than traditional buttonbush at 5 to 6 feet tall and wide, Fiber Optics is still a true wildlife magnet. Bees, hummingbirds and butterflies will sip nectar from the white spherical blooms. If planted near water, ducks and loons may eat the seeds in the winter. It requires the same general growing conditions as regular buttonbush, and its bright green leaves turn yellow in fall.
