Hydrangea serrata

Hydrangea serrata, commonly known as the Mountain Hydrangea, is a deciduous shrub native to the mountainous regions of Korea and Japan. Closely related to the more widely known Hydrangea macrophylla,H. serrata stands out for its delicate beauty, cold hardiness, and natural elegance. With its serrated leaves, lacecap-style blooms, and cultural significance, it has become a favorite among gardeners, horticulturists, and plant lovers across the world.

Hydrangea serrata is admired for its refined and natural form. Unlike the mophead hydrangeas with dense ball-shaped flowers, H. serrata often blooms in lacecap form—flat clusters of fertile flowers in the center surrounded by showy sterile florets, giving it a more understated, wild aesthetic.The leaves are slender, oval, and finely serrated (hence the name), turning shades of red and burgundy in the fall, adding seasonal interest even after the blooming season ends.

The blossoms of H. serrata usually appear in late spring to early summer, continuing into mid-summer. The color of the flowers—typically ranging from blue to pink to lavender—is heavily influenced by the pH of the soil.The lacecap flower form adds a dainty, poetic presence to gardens, with the smaller fertile flowers often being attractive to pollinators such as bees and butterflies.Over time, several cultivars of H. serrata have gained popularity for their color, form, and garden performance.
