Nine white hydrangeas to grow
White hydrangeas are more subtle than their blue and pink counterparts. We recommend nine to try.
Hydrangeas typically flower in pink or blue, with their colour determined by the alkalinity of the soil: on acid soils, flowers are blue, while in alkaline soils, flowers are pink. However they also flower in white, and these hydrangeas are arguably the most attractive of the genus. White-flowered varieties have a delicacy that pink and blue cultivars don’t have. They can be used to light up a shady area, act as a foil against brighter colors, and bring a sense of serenity to a planting area. Unlike pink and blue hydrangeas, most white varieties don’t change colour in accordance with the pH of the soil. However some blooms mature to a light pink or brown. Exercise caution when it comes to pruning hydrangeas, as the technique varies depending on the type.
