KnockOut TM  Radrazz'
'                         Home
 
Bloom and growth is fast and furious with this variety, almost to the point of being unstoppable!  This past spring (2003) our mother plants were under 5 feet of water for 36 hours.  The day after the flood waters receded there were already several blooms providing a show for us.  Blooms continuously from early Spring past frost. Knockout is as disease resistant as any we've seen.   It is drought and heat tolerant, treat it right and it'll knock its' self out trying to please you. Humidity has no effect on the plant....blackspot and mildew doesn't exist on this  plant, even when planted next to water! It's only shortcoming is a tendency to leafspot  during the winter months, not reall its' fault.  Fresh spring growth does not continue the spotting so it's easily handled with judicious trimming. If not the best shrub type rose presently on the market, it's definitely very close to the top!  Planted in groups of five or more Knockout is an eye stopper, continually attracting peoples attention here all the way from the road!
