This is excellent news for gardeners of all levels, both experts and novices! Everyone loves a low-maintenance plant, especially one as beautiful and fragrant as a rose bush. We briefly touched on this above, but Knockout roses are highly recognized for being resilient and resistant to diseases and pests. Just as with other shrubs, rose bushes that are planted in color mass groupings make for an excellent second level foundation planting or to establish a mid-sized border around your property. When planted 30-36” apart, they will give your landscape a beautiful boost of color and dimension. We recommend buying Knockout roses in color groupings according to the space you’re seeking to fill. When paired with larger shrubs like boxwoods, they provide elegance and beauty on par with traditional roses. When planted with flowers, like daylilies, coneflowers, and other perennials, the comparative density and height of Knockout rose shrubs provide an excellent backdrop. Knockout roses also pair well with a variety of other plants. This means that you get to enjoy a beautiful show of color for the entire season! Versatility On top of these benefits, they are repeat bloomers, producing fresh flowers every five to six weeks between spring and the first hard frost. They are also proven to be very cold hardy and can survive in many climates that traditional roses can not. Ease of Care and Hardinessįlowering Knockout rose bushes are extremely resistant to disease and drought, making them easy to care for. They have become a top seller across the nation and have many benefits compared to traditional roses. His creation of the Knockout rose revolutionized roses as a whole. His goal was to create a rose that was easier to care for and disease-resistant. Knockout roses were created by a rose breeder named William Radler. They’re simply low-maintenance, disease-, and drought-resistant enough that you can place them where other types would falter.What are the Benefits of Knockout Rose Bushes? Gardeners wouldn’t have dreamed of putting roses in parks and commercial raised planters back in the day either, but now they’re a common sight at shopping malls and in schoolyards. But parking strips and other arid areas are no challenge for Knock Outs. If you suggested planting an Old World cultivar in a parking strip 50 years ago, you would have been laughed out of the room. Knock Outs can grow in places where most people would never have dreamed of planting a rose in the past. Today, he continues his efforts, trying to bring new options like spotted and purple roses to market, two features that have eluded breeders. While Buck created some equally hardy and pest-resistant cultivars, Radler found the magic combination that converted even the most resistant growers. Griffith Buck, David Austin, and Wilhelm Kordes were all famously laboring for decades to improve existing types.īoth Radler and Buck felt that if a plant is too difficult to grow, people simply won’t grow it anymore, and they used this as a guiding principle. That’s not to say that others hadn’t been out there as well, doing the hard work to create tough roses. Since it was introduced commercially, nearly a billion of the shrubs have been sold in stores across the country, including big box retailers like Lowe’s and Home Depot, and many other colors along with one miniature have been introduced. Right away, it was a massive success with gardeners. Star Roses and Plants in Philadelphia took a chance on the new creation and started selling it in 2000. After over a decade of work, Radler unlocked the code to commercial success with “89-20.1,” which turned out to be a hardy, long-blooming, disease-resistant shrub with pinkish-red blossoms.
