Growing information:SHRUB hardy to minus 28ºC, growing to 1m-2.5m (3-8′) high, sometimes taller. The spherical flower-heads occur on branching stalks, or from the axils of the leaves. Each one is about 1–1½” across, and covered with sweetly fragrant, small white or cream flowers. The 4 short stamens and a single white style that is long and undivided, projects beyond the corolla, giving the flowers a starburst appearance. The fruit is like a narrow upside-down pyramid. Native to North America, where it is an important nectar source, Buttonbush also grows well in the British Isles, growing well in sandy, loamy soils or alluvial soils with sand or silt surfaces and prefers acidic or neutral soils but is intolerant of alkalinity. It prefers medium to wet moisture levels and is intolerant of dry soils. Abundance increases with increased water levels and increased light levels. It has historical medicinal uses but is toxic in large doses. Plant at 12′ spacing in sun or partial shade.
