Hydrangea macrophylla 'Blue Heaven' is a bushy deciduous shrub boasting large, bright blue flower heads. Flowering from early summer until frost, this bigleaf hydrangea is a prolific reblooming hydrangea, as it blooms on both old and new growth. Even if old growth buds are winter damaged, the plant still flowers in summer on new growth. The foliage is dark green with large, glossy, serrated leaves. Compact, this elegant mophead hydrangea creates drama in the garden. Perfect to create a lovely hedge or use as a specimen or accent for foundations and other locations near homes or patios.
