Knock out rose bushes & Rose Rosette
I am on a landscape committee near Nashville, TN. Can you tell me if there are any rose rosette resistant knockout rose bushes available? I was told a year or two ago a resistant variety had been developed. If yes what is the name and will it grow in zone 5? We would like to consider using it at our community entrances.
I think determining resistant varieties is still in progress. However, I did find a comprehensive article on rose rosette virus. Page 7 discusses *reported* resistant varieties. http://www.newenglandgrows.org/pdfs/ho_WindhamRoseRosette.pdf
