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 - this is also one of the most prolific reblooming hydrangeas we've ever seen. 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. Available in better garden centers in spring 2019.

Growing & Maintenance Tips for Hydrangea serrata 'Tuff Stuff Ah-Ha®'

Tuff Stuff Ah-Ha hydrangea does not need pruning except to remove any dead wood in early spring. You should not cut back or trim this plant at any time of the year, as doing so will remove flower buds. Hydrangeas are shallow-rooted and benefit from a 2-3" layer of shredded bark mulch. If you wish, you may fertilize in early spring, once the ground has thawed, with a granular fertilizer formulated for woody plants, like a rose fertilizer.
