Knock Out


Hello, my name is Knock Out Rose! I am known as one of the most popular choices of roses due to my low maintenance, extreme resistance to disease and lengthy blooming period. These features combined with the stunning appearance of my cherry red roses make me sure to be a knock out in any garden I am grown in. I am low maintenance, only needing to be pruned in late winter once the threat of cold weather has passed. I am tolerant of any soil or pH type, and will be happiest, healthiest and most beautiful when planted in an area where my soil will be kept moist and I can get as much sunlight as possible!
