Will my white hydrangea stay white?
Yesterday I bought a Hydrangea Macrophylla with white flowers. I have taken a few cuttings from it before planting the plant in a tub to sit on the patio. Will the flowers be white next year? I have blue and pink hydrangeas planted in the soil and am aware the colour of the flowers is determined to some extent by the type of soil. I would like these to remain white. Any advice would be welcome. Thanks.
