A Bigleaf (macrophylla) Hydrangea plant with flowers that form on the current year's growth as well as on old wood. Endless Summer® can bloom for months in warm areas, especially if deadheaded regularly, and the flower heads—blue on acid soils, pink on alkaline—are up to 9" across.
In Maryland, mopheads grow best in morning sun with some afternoon shade. Can tolerate more sun if the soil is consistently moist. 3-4 feet tall and wide, prune after blooming in August as needed. 3 gallon size.
