Hydrangea paniculata ‘Pink Diamond’ is a vigorous, bushy, deciduous shrub boasting huge conical flower panicles, 8-12 in. long (20-30 cm), from late summer into fall. Opening creamy white, the florets turn deep pink as the season progresses. Borne on strong, sturdy stems, the blossoms create a colorful show that extends well into the fall. This hardy hydrangea adds striking flowers to foundation plantings, shrub borders, and floral arrangements.
