How to Use Sunny Knock Out® Shrub Rose in the Landscape

You'll be amazed how versatile this Rose bush is in the landscape. Sunny features an energetic upright habit and bright yellow blooms that age quickly to a pastel cream color.

This plant "goes" with just about any other color you care to use with it. Style it any way you like, but don't forget to use the fragrant sprays in cut flower arrangements to decorate your interior tablescapes.

Try a chic contrast by pairing these with the beautiful blue blooms of Bluebeard. You'll love the crisp, pretty and timeless effect.

If your taste runs to the casual bohemian, why not layer in rougher-textured Black Eyed Susan. Punctuate with bold Coneflowers in both traditional purple and wild Sombrero Salsa Red! Add Neon Splash Spirea for very long-lasting blooms.

The burst of color will make you smile every time you look at it!

For an ultra-modern look, try a long row of Sunny Knock Outs all by themselves in a raised bed. You'll enjoy months of blooms and create a standout garden feature, without any special care.

Have poor soil? No problem. Try a partner pairing of Sunny Knock Out with McKay's White Potentilla. They'll easily provide "flower power" for you without asking for...really anything but sunshine and water from you.

This easy-care, compact, naturally rounded shrub Rose is an excellent planting choice for foundation planting, border planting or as an attention-grabbing focal point in your landscape.

Enliven your commercial landscape the easy way with a mass planting of Sunny Knock Out Shrub Roses. You'll draw eyes on your business with a bright boost of color to fill a wide, open area.

For a solid hedge or mass planting, plant two feet apart on center. You'll measure from the center of one to the center of the next. Mulch between plants and keep new mass plantings weeded until they grow together.

#ProPlantTips for Care

Easy-care, low maintenance and forgiving, the Sunny Knockout shrub Rose needs at least 6 hours or more of full sun each day. They also require well-drained soil that won't retain water for long.

We always recommend Nature Hills Root Booster when planting to get your Roses off to the best start. Follow the directions on the package.

For best results, give Roses a medium amount of water on a regular basis. This plant is moderately drought tolerant, but does best if you water deeply in times of extreme drought.

Wait until early spring to prune them. Simply trim down to 6 inches, just as they start to grow for the season.

Add two inches of mulch over the root system, and plan to reapply in spring. Over time, the mulch will break down to improve your soil!

This tough shrub is not bothered by common pathogens like black spot, powdery mildew or leaf rust. It truly excels in humid climates where other Rose varieties can't survive.

Apply a slow-release fertilize once a year in early spring. Follow directions on the label.

Get started on the landscape of your dreams! Use Sunny Knock Out Shrub Rose throughout your yard to tie the look together. It's a fabulous choice that performs beautifully.
