Hydrangea serrata 'Tuff Stuff Ah-Ha' Mountain Hydrangea

When it comes to blooming, Tuff Stuff Ah-Ha^® hydrangea can't stop, won't stop! 

At first glance, it would appear that we decided to introduce this beautiful mountain hydrangea solely for its waterlily-like double florets. But that's only part of the story - it's also a prolific rebloomer. All summer long, it devotes its energies to creating flower buds on its new growth so that you have a constant supply of fabulous blooms from early summer through frost. Tuff Stuff Ah-Ha^® hydrangea will bloom pink or blue, depending on soil chemistry.
