Culture Notes

This hydrangea grows best in full sun to light or open shade. A location protected from hot sun will keep the foliage and flowers from prematurely fading or scorching. A rich moist to well-drained soil produces the best growth and flowering. Hydrangeas are not drought tolerant and will grow and flower more prolifically with regular summer watering. This hydrangea can be kept smaller by pruning hard to 12 to 24 inches tall two to four years or it can be allowed to form a large shrub. If allowed to grow little pruning is needed, only remove dead broken or poorly formed branches. Old flowers can be removed in fall or winter once they are no longer attractive.
