Seaside Serenade Cape Lookout Hydrangea
Hydrangea macrophylla ‘Hortcodewo’Seaside Serenade Cape Lookout Hydrangea is a compact reblooming hydrangea prized for its large pure white mophead flowers, strong stems, and reliable season-long performance. Blooming on both old and new wood, it produces abundant rounded flower clusters from summer into fall, extending its display well beyond traditional hydrangea bloom periods. The clean white blooms hold their color well through the season and provide a bright, classic look in the landscape.
This compact shrub typically grows 3 to 4 feet tall and wide, forming a dense rounded habit with sturdy stems that help support the heavy flower heads without flopping. The deep green foliage provides a rich backdrop that enhances the brightness of the white blooms and remains attractive throughout the growing season.
Cape Lookout is especially valued for its dependable reblooming habit and strong garden performance. The large white mophead flowers are excellent for fresh cut arrangements and also dry well for long-lasting indoor use. Its compact size makes it especially useful where space is limited but strong floral impact is desired.
This hydrangea thrives in part sun with rich, moist, well-drained soil. Consistent watering during hot weather supports continuous blooming and healthy foliage. Minimal pruning is needed beyond removing winter-damaged stems and spent blooms in early spring.
