Hydrangea Overview

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. It has a rounded habit and is hardy to around -15 degrees Celsius, plant in a position of full sun to partial shade, in moist, well-draining soil for optimal growth. Originating from Japan, this is one of the most popularly grown Hydrangea plants, it is a common sight in many gardens and many cultivars have been developed from it for garden use. 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.
