Hydrangea paniculata 'Bombshell'

Discovered as a branch sport on Hydrangea paniculata 'Grandiflora' in Boskoop, The Netherlands, in 2003. Typically growing as a rounded mound to ony 2-3 ft tall and 3-4 ft wide. The dense and nearly rounded flower panicles cover the shrub in large clusters, starting out white, then becoming pink and white by the end of summer. 'Bombshell' blooms earlier and longer than most other paniculata cultivars. Yellow to purple fall color. Hardy to zone 4.
