A true remontant hydrangea, Bloomstruck flowers on both old and new wood, improving on the classic Endless Summer® to bring truth to its name. With blooms so large and vibrant that you won't believe you'll have all summer to enjoy them, Bloomstruck® hydrangea produces mophead-style flower heads alongside dark green leaves. Its color is dependent upon soil pH, producing rose-pink blooms in alkaline soils and violet or blue flowers in acidic soils. Endless Summer® also features lovely red-violet stems and attractive veining, providing a beautiful backdrop to all those gorgeous blooms. Size and shape maintenance are easy, and require only minimal pruning after the blooming season. Above-average heat tolerance and mildew resistance make this compact hydrangea the perfect addition to your summer garden. Hydrangea macrophylla 'PIIHM-II' PP255666
