Hydrangea macrophylla is a large-leaved, deciduous shrub species from the Hydrangeaceae family. It produces huge, showy flowerheads during the summer. These may be blue when the soil tends more towards an acid pH, white or pink if the soil tends towards an alkaline pH. Leave old flowerheads on to provide winter interest. The leaves hold water which makes it a popular choice for planting close to buildings, acting as a fire break. The leaves can be fermented and used medicinally.
