Repeat Blooming Hydrangeas
Are you frustrated because your French or mophead (Hydrangea macrophylla) hydrangeas only bloom once? Then the Endless Summer® Hydrangea series is the answer to adding repeat blooming hydrangeas to your landscape. With proper care, they will bloom from early summer to fall. The first flush of flowers in the early summer usually bloom on old wood; therefore, any necessary pruning should be done immediately after blooming. Flower buds will then form on new wood. As these blooms fade, deadheading is recommended to encourage more flower bud production. Flower color is determined by the availability of aluminum in the soil. If the soil is more acid, the flowers will be blue in color, but in alkaline soils, they will turn pink. If the soil pH is neutral (7.0), then the flowers will be purple.
