Double Down Hydrangea
Hydrangea macrophylla 'Hydrsrpdow'Double Down Hydrangea (Hydrangea macrophylla ‘Double Down’) is a striking mophead hydrangea known for its lush, double-petaled blooms that bring layered texture and vibrant color to the summer garden. Depending on soil pH, the large flower clusters range from rich blue in acidic soils to vivid pink in alkaline conditions. The full, rounded blooms appear from early to late summer, offering a long season of color that stands out beautifully against the plant’s dark green, glossy foliage. Its compact growth habit makes it ideal for borders, foundation plantings, and smaller landscape spaces where dramatic floral displays are still desired.
This hydrangea is not only visually impressive but also easy to maintain. Strong stems help support the dense blooms, keeping the shrub tidy and upright throughout the season. Double Down thrives in partial shade, particularly morning sun and afternoon shade, and adapts well to various well-drained soil types. With reliable flowering, compact form, and richly textured blooms, it brings elegance, structure, and vibrant seasonal interest to any garden setting, whether used as a specimen plant or grouped for bold impact.
