A great feature of BloomStruck and this collection is the ability to change the blooms’ color to your liking. Depending on soil pH, you can have vivid rose-pink or purple hydrangea flower heads. If your soil’s pH does not produce the hydrangea colors you prefer, try the Endless Summer Color Kits to change your acidity level and, in turn, change your bloom color! BloomStruck also has incredibly beautiful red-purple stems, dark green leaves with red petioles and red veins, which give great contrast to your other garden shrubs, perennials and annuals. Because of BloomStruck’s extremely strong stems, above average heat tolerance and great disease resistance – especially to powdery mildew – it is a perfect combination of beauty and hardiness for your garden!
