Particularly eye-catching, Hydrangea macrophylla 'Peppermint' features huge, rounded flower heads, up to 10 in. across (25 cm), densely packed with white florets adorned with pink or blue stripes, depending on the soil pH. Flowering from early summer until frost, 'Peppermint' is a prolific reblooming hydrangea, which 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. Slow-growing and 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.
