A deciduous shrub that is wide and upright, with a round habit. Large, oval leaves and showy flowers from June to September provide a stunning splash of colour in any garden. Perfect for beginner gardeners as their growing requirements are minimal: simply plenty of water and well drained acid soil. They require little light, pruning and manuring as well as no special treatment. Hydrangeas have a root system which spreads considerably, but they are also able to be grown in pots without the size of the flowers being affected. A showy classic. The plant itself falls within the H4 rating in terms of hardiness and is generally fine with the British climate but needs sheltering in extreme cold snaps. The plant is prone to potential pests but is generally disease free. Follow the guidelines of pruning group 4 for this plant. The final height of the plant is between 3 m – 4 m (9.8 ft – 13.12 ft) and the final width is between 3 m – 4 m (9.8 ft – 13.12 ft)
