Growing to 1.5 m (4.9 ft) tall and broad, it is a compact evergreen shrub with rounded matt green leaves and rose pink bell-shaped flowers in spring.
In cultivation in the UK, Rhododendron williamsianum has gained the Royal Horticultural Society's Award of Garden Merit.[3][4] It is hardy down to −15 °C (5 °F) but like most rhododendron species requires a sheltered position in dappled shade with acid soil that has been enriched with leaf mould.
The name williamsianum is in honour of the Cornish plantsman John Charles Williams, who developed many shrubs and trees of importance to horticulture.[5]
