The original Red Knock Out® Rose (Rosa ‘Radrazz’) is a reliable landscape rose known for long-lasting color and low-maintenance performance. Its rich cherry-red blooms appear continuously from spring until the first hard frost, standing out against deep, purplish-green foliage.

Red Knock Out® Rose is naturally bushy and works beautifully in mass plantings, borders, foundation beds, informal hedges, and mixed sunny gardens. It is self-cleaning, black-spot resistant, and drought-tolerant once established—meaning it provides strong landscape color without the frequent deadheading and intensive care associated with many traditional roses.

Sold in a 3-gallon container. Plant size, fullness, and bloom coverage naturally vary by season and nursery availability.
