Hydrangea macrophylla

Common name:
Bigleaf Hydrangea, Mophead Hydrangea, Lacecap Hydrangea

Description:
Hydrangea macrophylla is a classic, deciduous flowering shrub prized for its large, showy blooms that range from pink to blue, depending on soil pH. Mophead varieties produce rounded, globe-like flowers, while Lacecap types have flatter blooms with a delicate, lacy centre. This versatile plant thrives in moist, well-drained soil with good organic content and prefers a sheltered spot with morning sun and afternoon shade to prevent leaf scorch. Flowering occurs from late spring to early autumn, providing long-lasting colour in the garden. Regular pruning after flowering helps maintain shape and encourages strong new growth. Hydrangea macrophylla is ideal for garden beds, borders, mass planting, or as a striking feature plant in pots.
