Hydrangea paniculata ‘Grandiflora’, also known as the PeeGee hydrangea, is a classic large-growing shrub hydrangea, renowned for its longevity, hardiness, and spectacular blooms. This historic variety is distinguished by its very large conical panicles composed of flowers that are initially creamy white, evolving to pale pink, then to brownish pink at the end of the season. Its overall habit is upright, full, and heavily branched, and it can be grown as a large shrub or a small ornamental tree. Thanks to its imposing stature, it is particularly suitable for large beds, informal hedges, specimen planting, and large-scale landscape designs. Like all Hydrangea paniculata, ‘Grandiflora’ blooms on new wood, ensuring reliable flowering every summer. Its medium green deciduous foliage effectively supports the blooms and contributes to its majestic appearance. Very hardy and long-lasting, it remains an essential reference in nurseries.
