Knockout Rose Origins:Knockout Rose Sunny Yellow / Rosa 'Radsunny'


- The Knockout is a carefully bred rose that was a result of crossing old heirloom roses with more modern roses on a quest for a care free rose for all of us modern gardeners with little time and no knowledge of what roses need and how to take care of them....and that is exactly what William Radler got when he bred the Knockout line of roses. Thanks to his painstaking efforts you don't have to be an expert rosarian to have a beautiful and healthy Knockout Rose bush in your front yard landscape. You don't even have to be much of a gardener at all! Its the rose for the rest of us...so we can look like we know what we are doing without actually having to know what we are doing. Its my kind of rose... Try it you wont believe how well they thrive on....well nothing!


 - A little side note that maybe not all roses in the Knockout family are created equal. don't get me wrong, I'm a Knockout fan, but for some reason I have found that the sunny knockouts aren't quite as hardy or rebloom as readily without a light trimming as the other Knockout roses in the North Florida | Jacksonville | St. Augustine area landscapes. Not really sure why the variation in hardiness and growth habit but there sure seems to be one with the sunny, the white and the rainbow. SO for the rest of the country I'm sure these are stunning and carefree, but here  in our North Florida gardens they need a little more TLC than the rest.
