HYDRANGEA

Commonly known as Hortensia

All 2 year old plants. Hydrangeas flower pink or red on an alkaline (lime) soil. They flower blue or purple on an acid (peaty) soil. White varieties remain constant especially in semi-shade. We recommend the use of Hydrangea blueing agent for all blue varieties. Due to the difficulties of growing blue Hydrangeas in pots, the first flush of flowers may flower pink. All Flower JUL-OCT.
