12 in stock
Hydrangeas are naturally pink, but where the soil contains iron or aluminium salts they will produce blue flowers.
Vitax Hydrangea Colourant provides the solution.
Varieties naturally pale pink tend to blue best, the darker pink varieties turning to mauve/blue.
Best results are obtained with plants growing in acid soil.
