I’ve never been a rose fan, but I have to admit that Knock Out® series roses are practically perfect plants. The blooms of these shrubs, which are 2 to 4 feet tall and wide, keep coming from midspring until well into fall. In Zones 6 and warmer, they can bloom well into December, which means they contribute to the garden nearly nine months of the year. Knock Out® roses require no pruning to rebloom and are disease and pest resistant, so their value is assured. The new stems and leaves are purple, especially on the red-flowered cultivar ‘Radrazz’.
Name: Knock Out® series roses (Rosa Knock Out®)
