Seaside Serenade Cape Lookout Hydrangea

Seaside Serenade Cape Lookout Bigleaf Hydrangea (Hydrangea macrophylla 'HORTMABLO')

Seaside Serenade Cape Lookout is a compact mophead hydrangea with large, long-lasting blooms that open pale green, turn pure white, and finish with a light pink blush. Thick, dark green leaves develop dark bronze fall color, while sturdy stems keep flowers upright in beds and containers.

Distinctive Features

Prolonged color progression on robust, cut-worthy heads provides season-long interest, and foliage resists scorch and burn even during hot summer days. Naturally tidy habit reduces staking and grooming.

Growing Conditions
