Rhododendron dauricum
Also called Daurian Rhododendron
Dahurian Rhododendron is a compact, semi-evergreen shrub from Siberia, northern China and Japan that flowers in late winter or early spring before its leaves appear. It needs a sheltered spot in dappled shade and acid, leaf-mould-enriched soil.
Rhododendron dauricum is a species of flowering plant in the heath family Ericaceae native to forests and forest margins in Eastern Siberia, Mongolia, North China and Hokkaido, Japan. The Latin specific epithet dauricum means "from Siberia" – Transbaikal is also known as Dauria.
R. dauricum is the basis of the PJM hybrid (Rhododendron dauricum × Rhododendron carolinianum).
The cultivar 'Mid-winter', with bright pink flowers, has gained the Royal Horticultural Society's Award of Garden Merit. It is hardy down to −20 °C (−4 °F), but like all rhododendrons requires a sheltered position in dappled shade and acid soil enriched with leaf mould.
R. dauricum contains monoterpenoids daurichromenic acid (DCA) and confluentin (decarboxylated DCA) as well as rhododaurichromenic acids A and B which are structurally related to cannabichromene.
