Hydrangea macrophylla ‘King George’ is a mophead hydrangea with a compact, rounded habit and full round globes of pink flowers. In autumn the fiery orange and red tones of its foliage extend its season of colour. It’s perfect for growing in a mixed, herbaceous border, especially when used in conjunction with other hydrangeas. It makes an excellent cut flower.

For the most intense flower colour, grow Hydrangea macrophylla ‘King George’ in moist but well-drained, neutral to acidic soil. Prune away spent blooms in spring.

A note on toxicity: Hydrangeas can be toxic to cats, dogs and horses, although your pet must eat a very large quantity of the leaves, buds and/or flowers for poisoning to occur. It’s therefore not regarded as a high-risk plant to pets, and is generally considered safe to grow in a pet-friendly garden.
