New from Marc Colombel of France, who has been working with tetraploid rhododendron parents to produce new plants with more chromosomes. The results are good. Rwain has thick leaves and big flowers like one of its parents 'Lem's Monarch', but there is more yellow in the blooms. This addition of yellow adds a nice 'glow' to the trusses. This will become a 5-star plant as more people grow it and report about its assets. We have also noticed that the plant displays lush foliage all the way to the ground, so will become an excellent screening plant. And…(ta-da-da) this plant does not make any seed, so will never need deadheading! How great is that?
A funny fact: I thought the name was a French town or village, but Marc tells me that the name is an acronym for Rhododendron Without An Important Name.
