A true remontant hydrangea, BloomStruck® builds upon the legacy of Endless Summer®, delivering vibrant, long-lasting blooms from early summer through fall. This remarkable hydrangea produces large, eye-catching mophead flowers alongside lush, dark green foliage, ensuring a season full of color. Its soil-dependent hue shifts from rose-pink in alkaline soils to violet or blue in acidic conditions, offering a dynamic display throughout the season. Adding to its appeal, red-violet stems and distinct veining provide a striking contrast to its abundant blooms. With minimal pruning required after blooming, as well as above-average heat tolerance and mildew resistance, BloomStruck® is a low-maintenance, high-impact addition to any garden.
