The 'Endless Summer' Hydrangea (Hydrangea macrophylla 'Endless Summer') is the answer to a gardener's prayer--the first hydrangea to bloom from June till frost. It blossoms on both old and new wood and the flower clusters are up to 8 inches across and pink to medium blue depending on soil acidity. The blooms attract bees, butterflies, and birds and are also ideal for cutting and drying. The plant is compact, grows to 4 feet tall and 3 feet wide, and does best in full sun to partial shade with moist soil--i.e., don't let it dry out.
