Good Morning,

I'm not terribly knowledgeable on plants but I can tell you that the Hydrangea flower can change color based on the ph balance of your soil. You can actually change the color of the flower by making the soil more acidic or alkaline. Hope this helps. Happy Planting from Florida Furniture Packages

Thank you. But I would like to find out which name is this hydrangea variety. There are many varieties.

Hydrangea m. 'Endless Summer'
