Hybridized by William Radler; introduced by The Conard Pyle Co., Rainbow Knock Out Rose is a 2007 All-America Rose Selection. AARS roses have all been put through a two year examination where they were tested on their disease resistance, flower production, color, and fragrance. These tests are judged in 23 gardens across America with all climate zones represented.
Rainbow Knock Out Rose, a compact landscape shrub rose of Coral/Salmon petals with a yellow center, has short stems bearing glossy, dark green leaves. The small blossoms start out as pointed buds which develop into five-petaled flowers two inches in diameter.
This variety has the same resistance to disease as the other roses in the Knock Out family. It is also winter hardy to zone 4.
