Green Hydrangea Plants

White to Green

• Some varieties of hydrangea plants have white flowers that turn green when the blossoms age. The smooth hydrangea, which is native to the U.S., features such changing blossoms. Choose the Annabelle variety of smooth hydrangea to get bright white flowers in midsummer that will always turn green within a few weeks (three to four) of flowering.

Pinks and Blues and Shades of Green

• Most hydrangea plants produce flowers in shades of pink or blue. The color of the flower is determine by the amount of minerals in the soil. Sulfur creates blue flowers. Add lime to the soil for pink blossoms. All hydrangea flowers change color with age. Commonly, pink and blue flowers become green over time, particularly in hot weather. Every few years, a hydrangea plant which usually blooms in pink or blue may emerge one year with green blossoms. After a season or two, the flowers will return to normal.

Hydrangea Care

• For best results, place hydrangea plants where they will receive early morning sunlight and shade in the afternoon hours. Even when fully exposed to sun, hydrangea will survive if given plenty of moisture. Prune hydrangea lightly and regularly to keep the growth of the shrub under control. Keep soil moist, but not so wet that you can squeeze water out of it with your fingers.
