Hydrangea shrubs are popular ornamental plants grown for their large flowerheads. Hydrangea macrophylla is the most popular and most widely grown cultivars. Some are best pruned on an annual basis when the new leaf buds begin to appear. Pink hydrangeas have risen in popularity everywhere, and in Asia pink hydrangeas mean ‘you are the beat of my heart’. There are many uses for the hydrangea plants, and one of the most spectacular is hedging. Be imaginative and have one of the most colourful hedges – a fantastic mixture of colours!
