Product Overview

Rosa 'White Knock Out'
Pure white single blooms that really pop against the dark green and burgundy foliage; a lovely citrus fragrance; blooms continually from spring to fall; great for sunny shrub borders or containers

White Knock Out® Rose is a multi-stemmed deciduous shrub with an upright spreading habit of growth. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage.

This shrub will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. Gardeners should be aware of the following characteristic(s) that may warrant special consideration:

  • Spiny

White Knock Out®: Rose is recommended for the following landscape applications:

  • Accent
  • Mass Planting
  • General Garden Use
  • Container Planting

Features

White Knock Out® Rose features showy fragrant white flowers with yellow eyes at the ends of the branches from late spring to mid fall. The flowers are excellent for cutting. It has burgundy-variegated dark green foliage throughout the season. The glossy oval compound leaves do not develop any appreciable fall color. The fruit is not ornamentally significant.

Planting & Growing

White Knock Out® Rose will grow to be about 4 feet tall at maturity, with a spread of 4 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 20 years.

This shrub should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid.

White Knock Out® Rose makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
