Introducing Incrediball Storm Proof™, the hydrangea that tackles one of the most common frustrations with the genus: floppy blooms. Unlike traditional smooth hydrangeas, which often struggle to hold their heavy flowers upright, this incredibly sturdy variety is built to withstand even the heaviest summer downpours. Its strong, resilient stems keep blooms standing tall—during and after a storm—ensuring your garden remains vibrant and intact no matter the weather. While the blooms aren't as large as those of the original Incrediball®, they're still impressively large in proportion to this more compact variety. And with an abundance of these stunning blooms, Incrediball Storm Proof™ easily lives up to its well-established reputation. This hydrangea boasts a robust, vigorous growth habit with a rounder, denser form than other smooth hydrangeas, making it a perfect choice for smaller spaces or those looking for a lower-maintenance yet high-impact plant. Whether you're a hydrangea enthusiast or a newcomer to the genus, Incrediball Storm Proof® is a must-have for your garden, delivering beauty and durability all season long.

  • 3.5-4 feet tall and 3-4 feet wide at maturity
  • Hardy in zones 3-8, be sure to check your USDA zone to ensure success
  • Plant in part to full sun (4+ hours daily)
  • Space plants 3-4 feet apart for best results
  • Produces white flowers that age to light green from summer to frost
  • Maintains green foliage spring to frost
  • Blooms on new wood
  • Great for landscapes, hedges and cut flowers
  • Attracts bees and butterflies
  • Salt tolerant

Care: Fertilize with Proven Winners Continuous Release Plant food in spring and mid-summer. Prefers well-drained soil that does not remain soggy for any amount of time. To prune, simply cut back by one-third of its total height every spring, just as new growth begins to emerge on stems. Make cuts just about 1/4 of an inch above a bud. Dead or damaged wood can be removed at any time.

Customers praised these hydrangeas for arriving with "beautiful blooms" and thriving after planting. Many noted healthy plants that survived extreme heat. However, shipping issues were common—packages arrived damaged, plants "tossed around," or wilted from heat exposure. Some received undersized gallon plants or experienced plant death shortly after arrival, requiring refunds.

I’m so impressed with this Incrediball Storm Proof Proven Winners hydrangea! It arrived very well

I’m so impressed with this Incrediball Storm Proof Proven Winners hydrangea! It arrived very well packaged and healthy. I’m in zone 9a, and it has done exceptionally well this spring. The blooms are absolutely beautiful, and the plant has been thriving. I loved it so much that I ordered two more!

Incrediball Storm Proof Panicle Hydrangea arrived in good condition. Temperatures at my home were still in the high 90s, so conditions were not good for planting. I uppotted the planted and placed it in indirect light. It is thriving. I am eager for the weather to cool down so I can plant it in the my garden.

Thank you for sharing your review of your Incrediball Storm Proof™ Smooth Hydrangea. We're happy to replace it or issue store credit if you wish. :) Please respond to this email and let us know which works best for you!

Additionally, your original hydrangea will be just fine once it is planted and watered. Proven Winners plants are very resilient and typically bounce back. The vast majority of plants recover quickly once they are unpacked and planted.

I had been strongly considering the standard Incrediball hydrangeas that Proven Winners had offered, but had waited to pull the trigger due to their larger size being too big for the space I was looking to have them in. When Proven Winners announced a stronger stemmed, slightly more compact version of the Incrediball— I was sold.

I ordered these in the quart size. They came in and looked tiny, but don’t worry, they’ll take off the second they go into the ground. I have them spaced a touch closer than recommended due to wanting to create a formal hedge. So far they’re growing well. I’m in southern Kentucky zone (7A). They are planted in an area that gets afternoon full sun and are not wilting like my big leaf/‘macrophylla’ do (despite being planted in the shade). I was afraid these might do that as well, but they haven’t. I will say that I’ve kept them watered well and I’d imagine they would suffer without adequate watering.

The Hydrangea boxes arrived damaged—dented, torn, and on their sides—in violation of instructions to keep them upright. Soil spilled, creating a mess. Many stems were broken, blooms battered, and leaves scattered. The plants looked wilted and neglected. Additionally, the individual pots had lost most of their soil during transit, forcing me to refill with better potting soil. I like Proven Winner, but this isn't their best work.

The flower that I received died after one day of planting it. It arrived from FedEx dying from the heat in the truck. I planted the flower the next morning water it , put fresh soil, water it and put mulch around it. By early evening the flowers were dead. I bought the flower to dedicate it for my late wife who loved the plant. I followed the directions but didn’t survive. I may have to reorder it next spring if i have any money left. Left me disappointed on it.

The plants were great but got pretty tossed around in the shipping process. Definitely a carrier issue.

Whether they are storm proof remains to be seen, but they are definitely not FedEx proof.
