Zones 5b-9

Hydrangea macrophylla 'Double Down'® is an exceptional bigleaf hydrangea known for its distinctive, fully double blooms and dependable performance. The lush, layered flowers vary in color, ranging from deep pink to purple or blue, depending on soil pH—acidic conditions intensify blue hues, while alkaline soils enhance pink tones. These long-lasting blooms rebloom consistently throughout the growing season. With a compact, mounded form, this hydrangea typically reaches 3–4 feet in height and width. It flourishes from late spring to early autumn, offering vibrant color and beauty in the garden.
