Learn More about Hydrangea macrophylla (Big Leaf Hydrangea)

Hydrangea macrophylla, commonly known as Bigleaf or Mophead/Lacecap Hydrangea, is a popular ornamental shrub cherished for its large, showy flower clusters and lush foliage. Native to Japan, it thrives in temperate climates and prefers partial shade with consistently moist, well-drained soil. One of its most notable features is its ability to change bloom color based on soil pH—typically producing blue flowers in acidic soils and pink in alkaline conditions. Blooming mainly in summer, many cultivars flower on old wood, though newer varieties may rebloom on new growth as well. With proper care and hydration, Hydrangea macrophylla adds vibrant, long-lasting color and elegant structure to gardens, borders, and containers.
