Description

[edit | edit source]

Growing to 1.5 m (5 ft) tall and broad, it is a compact semi-evergreen shrub with purple flowers which open in late winter or early spring, before the dark green leaves appear.[3][4]

Phytochemistry

[edit | edit source]

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.[5]

Cultivation

[edit | edit source]

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.[4][6] 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.
