Big Daddy Hydrangea, Hydrangea macrophylla ‘Big Daddy’, is a show-stopping shrub that brings dramatic beauty to the landscape with its massive 12 to 14-inch mophead blooms. Depending on soil pH, the flowers will appear pink in alkaline soils or blue in acidic soils, allowing you to adjust the color with soil amendments or fertilizers formulated for acid-loving plants.
This hydrangea is perfect as a bold accent, a stunning informal hedge, or in mass plantings. Its oversized flowers also make an impressive addition to cut flower arrangements, bringing elegance indoors.
Big Daddy Hydrangea Care
Plant in well-drained soil that has been enriched with organic matter for best performance. Water regularly, especially during hot, dry periods, to keep the soil consistently moist. Fertilize in early spring with a balanced or acid fertilizer if blue blooms are desired. Remove winter-damaged stems in late winter or early spring. Pruning is generally not required but can be done after the first flush of blooms in summer to maintain shape.
Big Daddy Hydrangea Spacing
For an informal hedge or mass planting, space plants 5 to 6 feet apart, measured from the center of each plant, to allow room for mature growth and airflow.
