Buttonbush is a beautiful native shrub of wetland and riparian edges, and other low lying moist locations. It is named for the 1'' wide, spherical shaped white flowers that emerge in late June to early July.
The fruit is a spherical nutlet, which turns from green to rusty brown in color as it dries and matures.
Buttonbush is native to eastern North America as well as California and Arizona in the west. See map below for range.
