Knock Out Roses - Still the Best

The members of the rose clan are an intriguing bunch. These prickly prima donnas lure us with their beauty, enchant us with their aroma and then ....spear us with their thorns. With a 'come hither' look but a 'stay away' barbed body, roses definitely want to be admired but not touched.

So it is with that admonition that I urge you to admire - and even plant - one of the seven  members of Conard-Pyle's Knock Out® Family of Roses. Why?  Because they bloom from Spring until frost, are easy to grow, are low maintenance and display great disease resistance.

My favorite is the double Knock Out rose. Its multiple petals give it a luscious look and it can fit into any landscape. Plant them individually among shrubs, annuals and perennials in mixed beds.  Or plant them in large groups to create an eye popping hedge.

Rose Breeder, Bill Radler, created the original Knock Out rose in the late 1990s which then went on to win the prestigious 2000 AARS award and broke all records for sales of a new rose. Today the Knock Out® Rose is the most widely sold rose in North America.

The Knock Out® Family of Roses have a generous bloom cycle (about every 5-6 weeks) and will continue to bloom until the first hard frost. Additionally, all of the Knock Out® Roses are self-cleaning so there is no need to deadhead.

If unpruned, The Knock Out® Family of Roses can easily grow to be more than 3-4' wide x 3-4' tall. Periodic trims will keep them maintained at a smaller size. A once a year cut (to about 12-18" above the ground) in early spring (after the last hard frost) is recommended for maximum performance)

  1. My favorite is Rainbow. I know not many people plant this rose, hard to find and some growers say it does not perform for them. But, it sure does for me - even when the blooms are faded they stay on the plant which is not true of the other Knockouts. It is the first Knockout to bloom in the spring and the last to stop in November.


  2. We used KO's on the West street medians...I think about 4,000 from Chambers St. to Thames St.

  3. Richard - you planted 4000 KO's??!! impressive....

  4. I agree with Eileen at Gatsbys Gardens, the Rainbow Knock Out is my favorite, as well.

  5. I have planted rainbow roses too..I like to mix them with others because their coloring blends well...
