The Tuff Stuff Ah-Ha™ Hydrangea by Proven Winners ColorChoice® is a compact reblooming mountain hydrangea. This shrub blooms every year without fail. It also puts a lot of energy into creating new blooms throughout the year. The flowers are either pink or blue depending on soil pH. The blooms remind us of waterlilies.
This bush blooms from early summer all the way to first frost. It is the most prolific reblooming hydrangea we’ve ever seen! This shrub is native to Japan, and can tolerate very harsh winters even in zones 5 and 6! We love using these as an edging plant, creating a very colorful landscaping border. These are also great as container plants or in mass plantings.
Tuff Stuff Ah Ha Hydrangea Care
We recommend planting this in an area with at least 4 hours of sunlight to ensure the best flowering performance. In hotter climates, such as zones 8 and 9, you must provide afternoon shade for some relief.
Pruning Tuff Stuff Ah Ha Hydrangeas is not necessary. We do recommend trimming off dead branches and leaves throughout the year. If you do prune, you run the risk of cutting off flower buds for next year’s blooming season.
It is best to apply a layer of mulch around the plants. This helps retain moisture as well as adding an extra layer of protection during harsh winter months to the shallow roots.
Fertilize in early spring, before new growth starts to emerge. You can use general slow release fertilizer designed for woody plants that is found at most stores.
Tuff Stuff Ah Ha Hydrangea Spacing
We recommend planting these 2 to 3 feet apart, center on center. If you choose to grow as a small hedge or landscape border, you can plant 18 to 24 inches apart, center on center.
