Jumbo Double Knock Out Shrub Rose

A low-maintenance knockout in candy apple red
Everything you love about Knock-Out roses--in double and bigger than ever. This maintenance-free, shrub-style rose produces fully doubled, hot-red flowers with a sweet, spicy fragrance reminiscent of cinnamon candy. A "self-cleaning" rose, Double Knock Out won't require deadheading for a new round of blooms. This continually blooming rose has a nice, long flowering season, with blossoms that look great as cut flowers. Rounded, bushy, and extremely well-behaved, this shrub rose serves beautifully in a low hedge or as a pretty accent. Unsurpassed resistance to black spot, downy mildew, and other diseases.

Is Jumbo the Way to Go?
This rose is available in a Jumbo Bareroot size. Ideal for gardeners who hate to wait, jumbo bareroots have a considerable head start over our standard #1 size.

  • You'll receive a hefty bareroot with 6-9 "flower ready" canes
  • 150% more blooms in the first year, guaranteed
