Botanical Name: Rhododendron mucronulatum
Common Name: Korean rhododendron, rhododendron mucronulatum
Family Name: Ericaceae
Distribution/Origin: Northern China, Korea, Russia, Japan
Description: These are deciduous shrubs, often with twisting-rambling branches. Autumn leaf colour is often very good in R. mucronulatum. The scales on their leaves and twigs (that can be seen with a good magnifying lens), reveal that they belong to the subgenus Rhododendron (or lepidopes). In comparison to their nearest relative, the semi-evergreen R. dauricum, the leaf-scales are not so dense (2 - 4 times their diameter apart) and the flowers are larger in this species. There is considerable variation in these characters within these two species, and they hybridize to form swarms of intermediate types in nature. The widely, funnel-shaped, flowers are typically rosy-purple in colour, but can be pink and even white. They open successively from clusters of buds at the end of the shoots before the leaves expand. While they can be killed by frosts below -5C, damaged flowers are soon replaced by the next ones to open. Place plants where they are not too exposed to the night sky in order to protect the flowers from spring frosts.
Notes: Deciduous shrub
