Botanical Specifications

Hydrangea paniculata 'Bombshell' is a compact selection (3-5 feet) of this large, cold-hardy species. It produces enormous, conical flower panicles (12-18 inches) that open white in mid-summer, age to pink, and finally deep rose-red. The bloom period is exceptionally long—July through October. Unlike macrophyllas, paniculatas bloom on new wood, so they flower reliably every year regardless of winter severity.

Culture: full sun to part shade, well-drained soil. More sun and drought tolerant than other hydrangeas. Prune in late winter/early spring. Hardy zones 3-8. 'Bombshell' drops a floral bombshell in the late summer garden.
