Rhododendron dauricum, commonly known as Daurian Rhododendron, is native to east Russia, Mongolia, north China and north Japan.
The etymological root of the binomial name Rhododendron is derived from the Greek rodon ‘a rose’ and dendron ‘a tree’. Dauricum is derived from the Latin meaning ‘from the Daurian forest steppe’.
The landscape architect may find Rhododendron dauricum useful as an evergreen shrub with attractive flowers suitable for understory deciduous woodland planting schemes. It is particularly suitable for planting in soils with an acid pH.
Ecologically, Rhododendron dauricum is of little ecological value in the UK as its nectar is poisonous to bees.
