This amazing plant is covered with vibrant cherry-red flowers from spring, through summer and into fall – three seasons of gorgeous blooms. It forms a small bush, 3 to 4 feet tall and the same across. Unlike other roses it is resistant to black-spot and most other rose diseases. It will grow across almost all the country, from zone 5 to zone 9. It is happy in all kinds of soil and needs just the most basic care. If you love roses, but think they are too difficult, try the Knockout Rose and see how wrong you were. This rose has changed the meaning of ‘rose-growing’ into something simple that everyone can succeed at.

  • Cherry-red flowers smother a dense, rounded bush
  • Easiest type of rose to grow
  • Flowers continuously from spring to fall
  • Disease and pest resistant
  • Perfect choice for any garden

Plant your Knockout Rose in beds, among other shrubs, or among flowers. Use it to form a beautiful low boundary, or anywhere at all where you want continuous color and low-maintenance plants. Plant in a sunny location for the best flowering, but this tough rose will also grow in partly-shaded locations far better than other roses do. It will grow well in all kinds of soils, including heavy clays, and it is both cold and heat resistant. You will not believe how easy it is to grow your own roses, until you try the Knockout Rose.
