White Knock Out® Radwhite

Closely related to Meilland's famous Knock Out, the White Knock Out too features excellent disease resistance and an abundance of bloomings that make them stand out as unbeatable shrub roses. The bloom is semi-double, 6 cm in diameter, with 4-8 yellow-centered white petals; the foliage is glossy dark green, compact, medium and reaches a height of 70 cm. Excellent for borders, it is also suitable to be pot grown; in 2017 it has achieved the Certificate of Merit at the Bagatelle trials (Paris); Gold Medal in 2011 at the Rose Hills International Rose Trials (USA); selected by William J. Radler and introduced in the United States in 2009 by The Conard-Pyle.
