Flower color is up to you. If you want blue flowers provide an acidic soil. If you want pink flowers provide a neutral to alkaline soil. Anything in between makes purple. This Hydrangea is equally hardy as it is beautiful. The most heat tolerant of all the H. macrophylla (mophead hydrangeas) in our gardens.

An acid soil will create blue flowers while a neutral to alkaline soil creates pink flowers. Anything in between makes purple. Learn more about soil pH and how to adjust it. The plants will tolerate full sun in northern zones however appreciate some afternoon shade or filtered sun in warmer southern zones. We recommend at least 5 hours of direct sunlight per day or all day lightly filtered sun for best flowering.
