Quick Overview:

The ‘double version’ of the original Knock Out Rose. Bright, 3.5" cherry red double blooms cover this shrub rose throughout the season. This shrub rose is a compact grower but needs room to develop. Pruning after major flower flushes will promote full re-blooming flushes. It is best noted for its ability to bloom in as little as 3 hours per day of direct sun with excellent disease resistance. Flowers are followed by orange-red hips. Foliage is dark purplish-green in summer, turning purple to burgundy in fall.

Description

Grow in medium moisture, slightly acidic, well-drained garden loams in full sun to part shade. Unlike most roses, Knock Out will grow very well in part shade locations with excellent disease resistance. Water deeply and regularly (mornings are best). Avoid overhead watering. Good air circulation promotes vigorous and healthy growth and helps control foliar diseases. Summer mulch helps retain moisture, keeps roots cool and discourages weeds. Remove spent flowers to encourage rebloom. Remove and destroy diseased leaves from plants, as practicable, and clean up and destroy dead leaves from the ground around the plants both during the growing season and as part of a thorough cleanup during winter (dormant season). Prune as needed in late winter to early spring.
