Hydrangea macrophylla ‘COF-HM3’, commonly called Rock 'n Roll Hydrangea, has large mophead blooms. The large flower clusters come in bright pink, purple and dreamy blue, and stand out against a backdrop of luscious green foliage. This hydrangea reblooms in late summer, and its sturdy stems ensure that the blooms will never flop or droop. These low maintenance beauties are worth the space in your garden!
Rock 'n Roll has a mounding, upright, bushy shape. It reaches 4 - 5 high and as wide at maturity. This rock star is extremely cold-hardy down to -30° F. It prefers morning sun and afternoon shade and grows best in moist soil. Use these star performers in a privacy screen, pollinator garden, or cut-flower bed. Rock 'n Roll attracts butterflies and other pollinators, while deer don’t usually bother with it.
Rock 'n Roll™ Hydrangea Care
Rock 'n Roll Hydrangea prefers part-sun exposure and moist soil conditions. It can burn in the hot afternoon sun and will need regular water during the summer. Like most hydrangeas, Rock 'n Roll grows best in rich soil with plenty of organic matter. The pH of your soil will determine flower color: acidic soil brings out blue hues, alkaline soil leads to pink, and neutral soil promotes purple tones. Cover the root zone with a heap of mulch to reduce water evaporation and nurture the soil.
This mophead hydrangea blooms on old and new wood. Prune in early spring before the first flush of blooms. Cut back dead and damaged branches, and shape to control size.
Rock 'n Roll™ Hydrangea Spacing
Space these hydrangeas 4 feet apart, center on center, if growing as a tight hedge. For foundation planting, site shrubs at least 6 feet from your home with plenty of clearance from overhead eaves to ensure plantings will not get too dry. Hydrangeas will develop a deep root system and should only be grown in containers temporarily.
