Single cherry-red flowers shading toward hot pink, blooming without pause from spring to the first hard frost. Rosa 'Radrazz' is the original Knock Out® Rose, introduced in 2000 and the plant that started a family now eleven varieties deep. It grows 3 to 4 feet tall and wide in full sun, hardy from Zone 5 through Zone 11.
Bloom is continuous from spring until the first hard frost. The flowers are self-cleaning, so no deadheading, and there is a subtle sweet scent up close.
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.
New growth emerges with a purple cast before maturing to deep green, and the open single flowers let bees reach the pollen. It handles drought, heat, and poor soil once established. Cut the whole plant back by about a third in early spring to keep it dense. Shipped on its own roots.
