Radiance1908 4 to 6 feet Often called Pink Radiance, to distinguish it from its darker sport, this large, cupped, soft pink bloom of about 23 petals is a famous rose that your grandmother is sure to remember. A very healthy bush, Radiance is tolerant of poor conditions when it has become established. Our cuttings came from the garden of an 1871 house in Navasota, Texas, where the present owners grandmother planted this rose when it was first introduced.
