Knock Out Rose
Here it is, the rose for the rest of us. Since its introduction in 2000, the original Knock Out rose has been one of the best selling landscape plants in the United States. The mid-sized shrub is beloved because it made rose-growing easy. The Knock Out produces single petal red roses continuously for nine months, no deadheading required. And its resistance to black spot, that slayer of roses, is legendary. Its popularity led Star Roses and Plants to develop a dozen varieties of Knock Out roses in a range of colors, sizes and growth habits.
