'Thrive!', a healthy descendent of the 'Knock Out'® rose, is a new landscape type rose that is being introduced by Star Roses in 2012. The 17 'Thrive!' roses lining our driveway were planted earlier this year. The photos in this post were taken today, July 30, 2011, in Bakersfield, California. I am pleased with how it is performing despite the usual hot summer weather that we have been having.
The parentage of 'Thrive!' is ('Marmalade Skies' X 'Baby Love') X 'Home Run'. This variety has excellent disease resistance in Bakersfield, to the powdery mildew and blackspot prevalent here, and has good disease resistance in other locations tested, getting some blackspot on the East Coast, but still holding onto most of its foliage.
The foliage and blooms are nicer during the spring bloom cycle, but IMHO it's not doing too badly now either.
