Rose 'Rhapsody in Blue' This rose created a great deal of excitement around the world when it was first introduced. The colour is an irridescent purple that fades to slate blue and is almost certainly the closest yet to a blue rose. Pretty buds open to semi-double flowers that are produced over a long period.The odd petal is streaked white and there is a central boss of golden stamens. It will grow into a tall, bushy shrub that is very healthy. Sweetly scented.
