History

Illustrated historical scene for Pink Knock Out

Rosa 'Pink Knock Out' is a clear medium-pink shrub rose released in 2004 by William J. Radler and Conard-Pyle as a color sport of the original cherry-red 'Knock Out'. The single to semi-double bright pink blooms show a white eye at the base of the petals and ring of golden stamens, blooming continuously from spring to frost on the same compact, mounded, nearly disease-free plants that made the original so successful. The cultivar extended the Knock Out series into a color already popular in the landscape trade and became one of the best-selling pink roses in North America.

Like its parent, it requires no deadheading, tolerates drought, resists black spot and powdery mildew, and survives into USDA zone 4 without winter protection. Extended the Knock Out color range and brought disease-resistant pink landscape roses to American home gardens.
