Happy Hydrangea, happy owner. I purchased two of these plants. Both are planted on the North side of my house. Neither of them had many blooms when I bought them. The plants looked healthy and that's what mattered. Both are thriving and blooming very well. The one with the most shade is the happiest. The leaves are beautiful and the blooms are stunning. The color is a beautiful light blue.
Tuff Stuff Ah-Ha® Reblooming Mountain Hydrangea Hydrangea serrata

Details
Features
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.
Tuff Stuff Ah-Ha hydrangea is featured in our "Power Puff Girl" magazine ad.
Top reasons to grow Tuff Stuff Ah-Ha hydrangea:
- Creates new flower buds all summer long.
- Double florets look like pink or blue waterlilies.
- Flower buds are more cold-tolerant, which ensures good blooming even in USDA zones 5 and 6.

We recommend a minimum of 4 hours of sun each day for best flowering and color. In hot climates, shade during the hottest part of the day is imperative.
Maintenance Notes: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.
This plant does not require deadheading, though if you wish to remove spent flowers, you may - we made a video showing how to do this.

Fun Facts:Mountain hydrangeas, Hydrangea serrata, are native to the same areas of Japan as big-leaf hydrangea, Hydrangea macrophylla. However, big-leaf hydrangeas grow along the mild coast while mountain hydrangeas grow up in the mountains. As a result, they have naturally developed flower buds that are more tolerant to cold conditions than big-leaf hydrangeas, so they bloom more reliably in USDA zones 5 and 6.

Purchased a Tuff Stuff Hydrangea in April. There is no growth in 3 months, other than a few very tiny, distorted leaves. The ground cover nearby is taller than this shrub. I believe these were incorrectly sprayed with growth inhibitors at the original nursery. Very disappointing.

I ordered these from PW and, while they arrived in great condition and loaded with flowers, the branches flopped straight down the ground and haven't come up off the ground in the two months since I planted them. This is very disappointing as they look more like ground cover than a shrub.

I planted 4 different types of hydrangeas last year, 2 endless summer, 3 standard costco one, 3 PW Mars, and 1 of this AH-Ha- Tuff Stuff. After my other Hydrangeas had wilted and been long gone (endless summer held out too),, this one kept reblooming! I like that it blooms again on new growth, it makes it more hardy if something happens to it over winter like someone breaking a branch etc... My PW Mars plants are beautiful but I baby them and they are slower to grow (still worth it!), this Ah-Ha is pretty strong, I moved it and it is doing well. I was very impressed with this Hydrangea, I've been keeping an eye out for this years shipment at my local nursery but haven't seen it yet! Looking forward to seeing how it does this year being it's 2nd year and changing out the costco ones which have never really bloomed well with this one.

At first I planted this on the south side of our home. I have another hydrangea on that side that is doing great. This one however, was not a happy camper there. I believe the sun was too hot reflecting off our stone home. I moved it to the north side and off it went happily. I'm looking forward to next summer to see what this plant can do when it's in a happier space.

Grows well and seems to be blooming pink, with new growth on stem coming in.

I just received this plant this year as a test trial and it has bloomed right away. The one thing so far I noticed is that the blooms are pink, not blue, due to soil ph, but still very pretty
