Hydrangea cinerea

2 Photos


Hydrangea cinerea is closely related to Hydrangea arborescens and was formerly classified as Hydrangea arborescens subsp. discolor. This species is more compact than H. arborescens, reaching a height and width of just over 5’ in five years. Additionally, the stems and the backs of the leaves of this species are covered in small hairs that give the plant a grayish cast, inspiring the common name ashy hydrangea. H. cinerea is primarily found in the central and southeastern United States. Ashy hydrangea starts to bloom in mid-July, slightly later than many other hydrangeas in the trial, and produces lacecap inflorescences that attract numerous pollinators. This species is rarely encountered in the horticultural trade.
