Coral Knock Out® Rose opens brick orange and fades to coral, and the color runs stronger in hot humid weather rather than bleaching out the way most warm-toned roses do. Rosa 'Radral' grows about 4.5 feet tall and wide in full sun, hardy from Zone 5 through Zone 11.
Bloom is continuous from spring through fall. The young foliage emerges bronze-red before hardening to medium green, and there is a slight clean scent.
Knock Out roses were bred for disease resistance first. They hold clean foliage through humid summers with no fungicide, bloom continuously without deadheading, and need nothing beyond a hard cutback in early spring. That combination is why they took over the landscape trade.
This is the largest of the Knock Outs, upright to rounded, which makes it usable as an informal hedge or a back-of-border shrub where the smaller ones would disappear. Cut back by about a third in early spring. Shipped on its own roots.
