Lush, lavishly blooming Hydrangea offers big beautiful, eye catching, flower clusters, ideal for fresh or dried arrangements. The vibrant blooms are usually hues of blue, pink or white and their deep rich colors are often dependent upon the pH of the soil with blue being more acidic and pink being more alkaline. An application of aluminum sulfate in spring will lower the pH of the soil to a 5.2 to 5.5 range. Hydrangeas thrive in partial to full shade sites in consistently moist but well-drained, soil. 'Climbing' Hydrangea is a vigorous twining vine with white flowers and it will scramble up a brick wall or over a fence or arbor. 'Oakleaf' is a cultivar with a larger habit, elongated white flowers, and handsome foliage that turns red in autumn. 'Endless Summer' is a patented variety that blooms on both old and new wood, so pruning can be done at any time of year without sacrificing flower stems. 'Vanilla Strawberry' offers unique elongated pink and white blooms all summer.
