Hydrangea macrophylla 'Mariesii'
Bigleaf hydrangea (Hydrangea macrophylla 'Mariesii') is a species of flowering shrub. It has a compact, rounded shape and can reach around 3-4 feet tall. The foliage is composed of glossy green to dark green leaves that turn a deep red-burgundy in the fall. In the summer, it is covered in breathtaking mophead flowers in shades of pink and blue, depending on the pH of the soil. Pruning helps maintain its bush-like habit and can also promote better flowering. Thriving in full to partial sun and well-drained soil, the bigleaf hydrangea is sure to bring a pop of color to any garden.
