Hydrangea macrophylla ‘Nightingale’ is a multi-stemmed, vigorous shrub from the Lacecap group boasting lush, light-green, saucer-shaped leaves. In summer, it produces large, flattened flower heads with dark blue flowers arranged in a ring, which can shift from blue to pink depending on the soil’s acidity. The flowers appear on two-year-old wood. To maintain a tidy shape, thin out crowded stems and shorten where necessary in late winter. Hardy in cold sites, it thrives best in semi-shade with well-moisturized soil. Deciduous, Hydrangea macrophylla is native to East Asia.
