Hydrangea Bombshell is a stunning compact hydrangea which is smothered in creamy-white blooms throughout Summer, fade to pink in the Autumn. Hydrangea Bombshell is best grown in organically rich, medium moisture, well-drained soils in full sun to part shade. Can be trained as a small single trunk tree, but is best grown as a large, multi-stemmed shrub. This is one of the most winter hardy of the hydrangeas. Bloom occurs on current season’s growth, so prune as needed in late winter to early spring.
