Obsession: Panicle hydrangea. No fuss, sun-loving, long-blooming. What's not to love?
Pink and white hydrangea flowers next to tall grass.

You gotta love a showy, flowering beauty that’s hardy to zone 3 (unlike its mophead, blue-flowered cousin H. macrophylla), looks its best in autumn when the rest of the garden starts to burn up, works in schemes from cottage to formal, adapts to full sun or part shade, some can be trained into a small tree or left as a big, blowsy shrub, is a romantic cut flower, and attracts butterflies.

Panicle hydrangeas (Hydrangea paniculata) can be tall and wide or compact depending on the variety, which means there’s probably one for most situations. Most have large clusters of white flowers in summer that fade to shades of pink or red before drying to beige. If left to dry on the plant in fall, they’ll stay looking good all winter.

If the only hydrangeas you plant are blue, you’re missing out on one of the late summer garden’s true pleasures.

Angel’s Blush® Hydrangea and Limelight Hardy Hydrangea

Glam, Awesome Hedge

Whether to separate a property, cover a fence, or line the back of the house, some panicle hydrangeas fill in quickly forming a dense, flowery hedge. Use tall, wide varieties such as Angel’s Blush® Hydrangea and Limelight Hardy Hydrangea and plant a bit closer (about 5 feet on center) to get a tight hedge. As these go dormant in winter, back with an evergreen if privacy is a priority.

Limelight Hardy Hydrangea and Fire and Ice Panicle Hydrangea

Team Player

Because of their unique chartreuse blooms varieties such as Limelight Hardy Hydrangea and Fire and Ice Panicle Hydrangea are ideal companions in all-green planting schemes. This combination of fine-leafed grasses, variegated hostas, Annabelle hydrangeas and Limelight hardy hydrangeas is a cool, elegant, tall drink of water in early summer. These hydrangeas will turn to white then pink as the season progresses.

Baby Lace® Hydrangea and Bobo® Hardy Hydrangea

Anchor a Bed

It’s true that many hardy hydrangea including paniculatas can get very large but no worries–breeders have developed dwarf and more compact varieties that provide a strong vertical shape to mixed borders. Baby Lace® Hydrangea and Bobo® Hardy Hydrangea are just two that won’t overwhelm a border, and when all else fades in winter, the dried blossoms keep it interesting.

Limelight in the back, and Little Lime™ Hardy Hydrangea  in the front

Provide Spectacular Scale

Many borders need height and as the season progresses, some of the flowering stalwarts such as Knock Out roses, mophead hydrangeas, and viburnums begin to fizzle out. At just that somber moment, panicle hydrangeas burst into bloom, adding drama and scale. This gardener used Limelight in the back, and Little Lime™ Hardy Hydrangea  in the front for continuity of design.

Quick Fire® Hardy Hydrangea and Pinky Winky™ Hardy Hydrangea

Three Season Wonder

Here’s where it really gets good. In early fall, blooms change from snowy-white to shades of pink and red, gradually fading to a soft creamy-hue. When the rest of the garden is kaput, panicle hydrangea adds a touch of late-summer color. Great choices include Quick Fire® Hardy Hydrangea and Pinky Winky™ Hardy Hydrangea.

Keeping Panicle Hydrangeas Happy

  • Light: Grow best in sun to partial shade. The ideal spot would be one that receives direct morning sun and afternoon shade.
  • Soil: Not as fussy about soil pH as some hydrangeas, but it must be fertile, well-fed, and slow to dry out. Amend with organic planting mix as needed when installing and add several inches of organic compost each spring.
  • Mulch: Add a 2-3 inch layer in spring to preserve precious moisture in summer.
  • Pruning: Blooms on new wood each year, so in late winter or early spring prune to encourage new growth. Larger varieties can be kept compact by pruning; this produces larger, if fewer, flowers.
  • Leave papery, faded flowers on stems in the garden for winter interest.
