White flowers bloom in May-July, attracting pollinating bees, wasps and beetles to this small shrub.

See Details Below


In May-July, clusters of tiny white fertile flowers bloom on the tips of branches, some with scattered sterile flowers appearing at the cluster margins, adding visual appeal. Flowers may continue to bloom throughout the summer. Seed capsules ripen in the fall. Smooth Hydrangea is native to moist woodlands and stream banks. It prefers moist, well-drained soils in part shade, although it tolerates full sun with consistent moisture. Intolerant of drought. This medium to large shrub may die to the ground in cold winters, and can be cut down to the ground to revitalize growth. Blooms occurs on new wood, so it’s best to prune in late winter. Plant as part of a mixed shrub border, within a partly shady woodland edge, or as a  backdrop for your perennial garden. Wildlife Value: The flowers are attractive to pollinators including bees, wasps, and beetles.
