Knock Out Rose

Rosa 'Knockout'

Knock Out Rose

Introduction

Knockout Roses look good any time of the year. Many areas enjoy blooms up to 9 months a year. Winter foliage starts as a dark burgundy then lighten ups to orange-red. Grows to a tight, compact 3-4 foot high shrub/hedge. A highly versatile plant that works where ever you put it.

Since the plant will continue to bloom throughout the growing season, there is no need to trim off old or dead flowers. New flowers are continually pushing the old ones out of the way.

Naturally resistant to diseases and pests that attack other roses, such as: mildew, fungi, blackpot, Japanese beetle, rose midge and leafhoppers.

Long periods of rain, drought, extreme heat or extreme cold no longer matter. Knockout Roses thrive from Florida to Canada, in full sun or partial shade. Plant where you need low shrubs, annuals, or perennials.
