Hydrangea Macrophylla Blue | Mophead Hydrangea

Wonderfully satisfying, slightly toothed deep-green foliage emerges from chunky, pointed leafy buds as the hydrangea awakens from its winter slumber. In summer, from pale lime green flower buds, bold, blue blooms colour up to give a lovely mid-to-late summer show. These deciduous shrubs look great either planted in pots or as a specimen plant in a border. Hydrangeas give their best blue flowers on acidic soils with a pH of 5.5. When grown on neutral soil or arriving in our mildly acidic mix, the flowers will predominantly be pink, although you may also get blue or mauve blooms. If you want to make sure that your hydrangea has blue-toned flowers, you will need to make sure your pH does not creep above 6.5. To lower the pH on neutral soil, you can treat it annually with a hydrangea flower colourant containing aluminium salts. Please note that the pot in the photograph is not supplied with the plant (which is sent out in a simple nursery alternative), but we have a wide and wonderful range on our website to choose from.
