The Double Knockout Rose is covered with beautiful fully-double flowers in a stunning fire-engine red color. It comes into bloom around the end of May and will still be blooming when the first frost hits it – three seasons of bloom. It forms a full bush up to 4 feet high and as much across. Unlike other roses it is resistant to black-spot and most other rose diseases.

  • Large and brilliant bright-red blossoms
  • Real rose form on a tough and easy bush
  • Continuous bloom from May to frost
  • Drought and heat resistant
  • Disease-resistant so always beautiful
