Hydrangea makes a wonderful color splash during summer and autumn. They like moist soils and partial shade. Some of the cultivars of Hydrangea macrophylla are the most popular to grow. Hydrangea is also known as Hortensia. It is part of the Hydrangeaceae family of plants. It is native to the Americas and Asia.
The blue variety thrives in acid soils. Hydrangea macrophylla Mariessii with large flat heads turns colors depending on the acidity of the soil. On slightly chalky or alkaline soils can turn more pink and red. Most varieties change color except white. By adding alum (aluminum sulfate) in early spring you can help them change color to blue. Most of the Hydrangea varieties grow to 2m or 6ft. in height. Hydrangeas are toxic to pets and horses.
How to grow Hydrangeas:
Hydrangeas are easy to grow and hardy. Grow Hydrangea in full sun or partial shade. But they don’t like heat, so keep them in shade in the afternoons. Plant them in moist, fertile but well-drained soil. Plant them in early spring. They thrive on deep watering. But never let them get soggy. Transplant them only when they are dormant.
