Growth Rate
Growth is moderately fast; expect almost 12 inches per year once established.
Leaves, Stems and Fruit
Leaves emerge in late spring and are glossy green with ovate to elliptic leaf shape. Tiny fragrant white flowers appear on a spherical ball-like head in early to mid-summer. These flower heads mature into ball-like fruits of multiple, two seeded, nutlets.
Use
Wildlife - It's flowers attract butterflies and other insects which, in turn, attracts various songbirds and bees.
Windbreaks - It may be used to provide good windscreen or windbreak component, especially in wetter soils.
Riparian Planting -Since button bush is native to stream banks, its fibrous roots hold soil in place. Adapted to periods of flood followed by drier periods.
Adaptation and Soil
Thrives in moist soils, including wetlands. Tolerant of moderate drought once established. Adapted to most soil pHs, but cannot abide high salinity. Also tolerant of both sun and shade.
Spacing
Normally spacing is 4 feet between plants.
Culture
One-year-old, bare-root seedlings, 12 to 18 inches tall are used in conservation plantings. Control of weed and grass competition is important for good survival and growth.
Pests
None serious
