Incrediball® Storm Proof™ Hydrangea
Hydrangea arborescens 'SMNHAGOV
Incrediball® Storm Proof™ is the smooth hydrangea I would reach for when someone loves the big white hydrangea look but does not want to watch the plant collapse every time a summer storm rolls through. The stems are the story here, but I also like that it stays a little more compact and gives better flower coverage than the classic big white types. Give it steady moisture, enough sun to build strong stems, and a late-winter or early-spring pruning, and it should make a clean, dependable summer show.

Incrediball® Storm Proof™ Hydrangea Brings White Blooms, Strong Stems, and Better Storm Performance
A Stronger-Stemmed White Smooth Hydrangea
Incrediball® Storm Proof™ Hydrangea is a white smooth hydrangea bred for sturdy stems, heavy flowering, and better performance after summer rain and wind. It delivers the classic round white hydrangea bloom look homeowners love, but with a denser, stronger framework that helps the flowers stay upright.
This makes it a practical choice for foundation plantings, flowering hedges, low borders, mass plantings, cut flower gardens, and high-visibility spaces where flopping blooms can be frustrating. The plant has a full, compact habit that fits easily into everyday landscapes while still giving you a bold summer flower show.
White Mophead Blooms From Summer Into Fall
The flowers open with a soft green-white cast, mature to clean white, and age back toward green as the season progresses. This color shift gives the shrub a long-lasting, elegant display that works beautifully with evergreens, boxwood, ornamental grasses, blue-flowering perennials, purple coneflowers, black-eyed Susans, catmint, lavender, and other sunny garden companions.
The blooms are useful fresh or dried. Cut them for arrangements when they are fully developed, or let them age on the plant for late-season texture. Their rounded mophead form brings a polished, classic hydrangea look to borders, patios, and summer garden beds.
More Flowers, Better Coverage, and Pollinator Value
Incrediball® Storm Proof™ was selected for abundant flowering and superior flower coverage. The result is a dense shrub with flowers distributed across the plant rather than only a few oversized blooms at the top. That gives the plant a fuller look in the landscape and makes it easier to use as a hedge or mass planting.
Unlike some mophead hydrangeas that are mostly sterile, this smooth hydrangea also includes a meaningful number of fertile flowers. That makes it a stronger choice for gardeners who want the big white hydrangea look while also adding more pollinator value to summer plantings.
Blooms on New Wood for Reliable Flowering
Because Incrediball® Storm Proof™ Hydrangea blooms on new wood, it flowers on the current season’s growth. That makes pruning simpler and helps support reliable bloom even after cold winters or spring cleanup. You do not need to protect last year’s flower buds the way you would with many bigleaf hydrangeas.
Prune in late winter or early spring before new growth begins. Cutting the shrub back by about one-third helps build a strong woody base while encouraging fresh stems and abundant flowers. Avoid pruning too late in spring once new growth is already underway.
Compact, Cold Hardy, and Easy to Place
Incrediball® Storm Proof™ Hydrangea typically grows about 3.5 to 4 feet tall and 3 to 4 feet wide, making it slightly more compact than many traditional white smooth hydrangeas. It is hardy in cold climates and works well in full sun to part sun, especially when the soil stays evenly moist and well-drained.
Use it as a specimen, a grouped foundation shrub, a flowering hedge, a container feature, a border plant, a cut-flower garden, or an anchor. In hot climates, morning sun with afternoon shade is best. With steady moisture, spring pruning, and enough light, this hydrangea gives homeowners a strong, clean, summer-blooming shrub without complicated care.

How to Care for Incrediball® Storm Proof™ Hydrangea
Be sure to read our planting instructions to ensure a healthy and happy Incrediball® Storm Proof™ Hydrangea plant for years to come!
How should I plant Incrediball® Storm Proof™ Hydrangea?
Plant Incrediball® Storm Proof™ Hydrangea in full sun to part sun with moist, well-drained soil. In cooler climates, more sun helps build stronger stems and better flowering. In hotter regions, choose morning sun with afternoon shade to reduce heat stress. Dig a hole two to three times wider than the root ball and about the same depth as the container. Set the top of the root ball level with the surrounding soil, backfill with native soil, water deeply, and mulch with 2 to 3 inches of mulch while keeping mulch away from the stems.
How often should I water Incrediball® Storm Proof™ Hydrangea after planting?
Water Incrediball® Storm Proof™ Hydrangea deeply after planting and keep the soil evenly moist during the first growing season. Smooth hydrangeas need consistent moisture to support large flower heads, full foliage, and strong summer performance. Once established, continue watering during dry spells, especially in full sun, containers, sandy soil, or hot climates. The soil should stay moist but not soggy. Do not let the root zone dry out completely during summer heat.
When should I fertilize Incrediball® Storm Proof™ Hydrangea?
Fertilize Incrediball® Storm Proof™ Hydrangea in early spring as new growth begins. Use a granular rose fertilizer, a hydrangea fertilizer, or a balanced slow-release shrub fertilizer according to the label directions. In rich garden soil, one spring feeding is usually enough. Avoid heavy late-season fertilizing because it can encourage tender growth at the wrong time of year. Good moisture, proper pruning, and enough sunlight are more important than repeated fertilizer applications.
When and how should I prune / cut back Incrediball® Storm Proof™ Hydrangea?
Prune Incrediball® Storm Proof™ Hydrangea in late winter or early spring before new growth begins. This hydrangea blooms on new wood, so spring pruning encourages fresh growth and same-season flowers. Cut the shrub back by about one-third to build a strong base and encourage abundant new flowering stems. Remove dead, damaged, weak, or crossing stems at the same time. Avoid cutting it back after spring growth is well underway unless you are removing dead wood.
