Hydrangea serrata Grayswood

Grayswood Hydrangea

Hydrangea serrata ‘Grayswood’ is a deciduous shrub known for its elegant lacecap flower heads that open white and gradually deepen to pink, rose, and reddish tones as the season progresses. This mountain hydrangea blooms in early to mid-summer, with fertile center flowers surrounded by larger sterile florets that develop stronger color with age. Its refined flower change and smaller foliage create a delicate, layered appearance in shaded gardens.
