The blooms tip down in a distinctive arching fashion and the shrub's narrow leaves and an abundance of flowers reliably cover the plant every summer. An excellent refined choice for landscapes, containers, borders, and wherever a delicate shape and color will compliment your plantings.

Care:  Fertilize with Proven Winners Continuous Release Plant Food in spring and mid-summer. Avoid pruning mountain hydrangeas, except to remove any dead wood. These hydrangeas cannot be cut back or trimmed at any time of the year without impacting the bloom for either the current season or the next. Soil pH affects flower color.
