This rose is a recent introduction. It is one of the Knockout roses, rosa 'radsunny'
The buds open to a clear yellow flower which carries a lemony fragrance. The bush is more upright in growth and not quite so vigorous in growth as the other knockout roses but still carries all those wonderful properties of disease resistance.
The plant weathered our extreme summer temperatures and now that cooler days and nights are here it is putting on quite a show.
