Hydrangea macrophylla (commonly known as Bigleaf Hydrangea) is a classic garden shrub prized for its lush, rounded clusters of flowers that bloom in shades of blue, pink, purple, or white, depending on soil pH. With its large, glossy green leaves and showy summer blooms, it brings a bold splash of colour to garden beds, borders, and pots. Hardy and adaptable, it thrives in part shade with moist, well-drained soil, making it a favourite for cottage gardens and elegant landscapes alike.
