This plant is a compact shrub, reaching about 1.5 meters in both height and width. Its flowers are purple, sometimes bright pink in cultivated forms, and appear before the leaves. The foliage is dark green and semi-evergreen, meaning it may keep some leaves through winter. The shrub has a tidy, bushy shape and stands out for its early-season blossoms.

Where does Rhododendron dauricum come from?

Rhododendron dauricum is found growing wild in the forests and edges of forests across eastern Siberia, Mongolia, northern parts of China, and Hokkaido in Japan. The species name 'dauricum' refers to Dauria, a region in Siberia. Over time, it has been introduced to gardens in other cold regions for its resilience and early flowering.

When and how Rhododendron dauricum blooms

The shrub flowers in late winter or the start of spring, before its leaves are fully out. It prefers acidic soils rich in organic matter, such as leaf mould, and grows best in sheltered spots with dappled shade. Gardeners often choose it for its ability to withstand cold temperatures, down to -20°C.
