Description

Growing to 1.5 m (4.9 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]

Cultivation

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][5] 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.
