About this plant
Hydrangea macrophylla 'SC-04-20' produces large mophead flower clusters from late spring through summer, displaying rich raspberry-pink tones in alkaline soils or vivid purple-blue in acidic soils while reblooming on both old and new wood. Glossy, deep green leaves with red petioles create a lush backdrop that support the abundant blooms without flopping. The dense foliage remains attractive throughout the growing season, while the extended flowering period provides months of vibrant color in the landscape.
Developed through modern breeding in the United States, this cultivar was selected for its reliable reblooming habit, strong stems, and enhanced disease resistance. It is well suited to mixed borders, foundation plantings, woodland gardens, patio containers, and cutting gardens, where its colorful flowers, handsome foliage, and long season of bloom create lasting ornamental interest from spring into late summer.

Shade Gardens · Foundation Plantings · Cut Flower Gardens · Cottage Gardens

Design tip
Take advantage of ‘Pebble Beach’s’ strong stems by using it where substantial flower heads can provide structure without staking. Its sturdy, upright display works especially well for adding a defined flowering layer to looser, more naturalistic plantings.
