Hydrangea serrata ‘Beni Gaku’

Beni Gaku Mountain Hydrangea

Hydrangea serrata 'Beni Gaku' is a deciduous shrub admired for its delicate lacecap flowers and beautiful color transitions. The blooms feature a central cluster of tiny, fertile flowers surrounded by larger, sterile florets that open white and gradually turn pink, then deepen to a rich red as the season progresses. This creates a striking multicolored effect within each bloom. The dark green leaves serve as an elegant backdrop to the flowers, and in the fall, the foliage turns a vibrant reddish-purple, adding seasonal interest.
