The Double Knock Out Rose

On Thursday, we planted two Double Knock Out Roses (Rosa Radtko PP#16202, CPBR#3104). We will most likely be buying a third Double Knock Out Rose to make a full hedge.

Marian Name: Mary's Rose

Description: From the same cross that produced the original Knock Out, The Double Knock Out Rose represents the next generation in the family of the The Knock Out Roses. The full double flowers look just like a classic rose. What it gained in beauty it did not lose in performance. It is as resistant to black spot as the famous original and is slightly more winter hardy.

Zone: 5-9

Light: Needs 4-6 hours of full sun for best blooming.

Water: Water well when planting, then as needed until plant is established. Water only at the base of the plant. Do not water overhead.

Flowers: Bright cherry red flowers from mid-spring until the first frost.

Spacing: Plant 3' apart.

Size: 3'-4' wide x 3'-4' tall.

Care Instructions: If unpruned, The Knock Out Family of Roses can easily grow to be more than 3-4' x 3-4' tall. To maintain size and for best performance, cut back once a year or once every three years (to about 12-18" above the ground) in early spring (after the last hard frost).
