Hydrangea paniculata Grandiflora

Common name:
Pee Gee Hydrangea, Hydrangea 'Grandiflora'

Description:
Hydrangea paniculata 'Grandiflora', commonly known as Pee Gee Hydrangea, is a striking deciduous shrub or small tree renowned for its large, conical clusters of creamy white flowers. These blooms emerge in summer, gradually transitioning to soft pink and then a warm, russet tone as autumn approaches, adding seasonal interest to the garden. Unlike mophead hydrangeas, 'Grandiflora' is highly tolerant of full sun and thrives in a variety of soil types, provided they are well-draining and rich in organic matter. It is a vigorous grower, making it ideal for hedging, specimen planting, or even training into a small tree. Regular pruning in late winter or early spring helps maintain a strong structure and encourages prolific flowering. Its ability to withstand cooler temperatures makes it a fantastic choice for Melbourne gardens.
