Incrediball Storm Proof™ Smooth Hydrangea (Hydrangea arborescens) | Proven Winners® New Variety 2025

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.
