Hydrangea Macrophylla 'Grenan' The Nantucket Blue™ Hydrangea is a repeat blooming selection of hydrangea that adorns houses on the island of Nantucket. Unlike most hydrangeas, this unique beauty blooms repeatedly on new growth throughout the growing season; may bloom from early summer well into early fall. Nantucket Blue™ grows best in afternoon shade or in dapple sunlight beneath large trees. Planting on the east or north a side of a home also works well. Use this plant as an accent plant, in mass plantings, or near water gardens or ponds.
Macrophylla hydrangeas are best pruned right after they are finished blooming. Cut the branches back by about one-third their total length. This plant tolerates a wide range of conditions, but does not grow well in soggy soil or full hot sun. Plant in full sun in zones 4-9; afternoon shade is preferable in warmer areas.
Dense leathery green foliage provides contrast for an abundant summertime display of blue or pink flower clusters that last until frost. Blooms on both old and new wood, near and far from the coast.Blooms on new wood. Flowers blue, pink and purple in early summer. This plant was bred to have really strong stems, perfect to hold up the enormous flowers this shrub produces.
Chewing hydrangeas causes cyanide to be released. The leaves, buds, flowers, and bark all contain the toxin, so if your dog munches any part of your hydrangeas, he could get sick. Unfortunately, deer love to graze on the leaves, flowers, and tender tips of hydrangeas.
