Not only is it unnecessary to dead head (remove the mess after the flower withers) this rhody – you won’t want to because the seed capsules (the part left over after the bloom is finished and is busy growing the seed) are quite blue. The oval leaves also have a bluish cast with a yellow midrib. This is a tidy, formal sort of fellow with stiff branches that become part of an upright shrub. R. cyanocarpum is not widely distributed in China. It most likely lives only on the Cangshan in Yunnan.
It prefers an open location that is bright but it doesn’t like the hot afternoon sun. Plant in light, well- drained soil, and give it small amounts of fertilizer on Valentine’s Day and Mother’s Day. It may reach 4 – 5 feet in ten years.
