Soft pink flowers with hints of green.

Hydrangea macrophylla Seaside Serenade® Cape Lookout

Soft-pink flowers with hints of mint-green offer a calm, meditative effect in a garden setting. A repeat bloomer, this stunning Hydrangea continues to produce firm new blooms throughout the summer.

Named in commemoration of Oregon’s national seashore preserve, Cape Lookout Hydrangea offers something special for everyone. Soft-pink flowers with hints of mint-green offer a calm, meditative effect in a garden setting. A repeat bloomer, this stunning Hydrangea continues to produce firm new blooms throughout the summer from buds set below the ground the year before - perfect for cutting to bring indoors. Later in the season, as the flowers mature, the pink fades, turning mint-green with soft, red edges – another opportunity to take advantage of their long, extended vase life, which can last up to a month or more! Offered exclusively through the Monrovia® Plant Collection. Pruning: Plants can be pruned to 12-15” in late fall/early spring as long as you add mulch in the fall.

This plant is sold exclusively in the Monrovia® Plant Collection.
