Hello all, in case anyone has these in a grouping, I could use some advice. I am thinking of pairing Canadian Sunset (5') with Seaview Sunset in front (2'). I would like to add to them one more specimen, something larger than 2' but not necessarily larger than 5' at maturity, in a mostly solid colour that would match the darker pink/plum tones in the other two rhododendrons. Has anyone got any recommendations?
