The 'Blushing Bride' Hydrangea (Hydrangea macrophylla 'Blushing Bride') is another in the Endless Summer series that bloom on old and new wood and so provide flowers all summer. In full sun or part shade it grows 3-5 feet tall and as wide. The blossoms are 8 inches wide and snow white, soon acquiring a very subtle (and beautiful) pink blush. Note: if the soil pH is acid, the blush, and eventually the color of the entire bloom, will be sky blue.
