Growing & Maintenance Tips for Hydrangea macrophylla 'Paris Rapa'

All hydrangea naturally undergo some colour change to their flowers as they age. Adjusting the pH balance of the soil (the addition of aluminium sulphate) can change the flower colour from pink to red in this cultivar. Most cultivars thrive in full sun to partial shade as long as they have adequate moisture and a rich, well-drained soil.
