Notes
'Double Knock Out' rose (Rosa 'Double Knock Out') is a shrub for borders, containers, cottage gardens, and hedges. It is hardy to USDA zone 5, or down to -20°F (-29°C). This plant likes full sun and average to moist soil of most types. The fragrant red blooms appear in spring, summer, and autumn, and butterflies and bees visit them. Its self-cleaning flowers keep it tidy, so it needs little care. William J. Radler bred it.
Pairs well with Yarrow, Feather reed grass, and Stained Glass hosta.
