Hydrangea Macrophylla ‘Little Blue’

One of the most compact hydrangeas, this little gem is ideal for adding a splash of colour to the front of a border, lining the edges of a path, or offering a long season of interest to the patio or balcony. As the flower colour is influenced by the soil’s pH, it is important that this is grown in acidic soils (or ericaceous compost in a pot).

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.
