Azalea japonica ‘Blue Danube’ – A Jewel of Spring Colour

Azalea japonica ‘Blue Danube’ is a striking evergreen azalea cherished for its vivid flower display and compact growth. In late spring, it bursts into bloom with masses of violet-blue to purplish flowers that smother the foliage in a dazzling show.

Its small, glossy green leaves provide year-round structure, making it as valuable in winter as it is in spring. Naturally compact and slow-growing, ‘Blue Danube’ thrives in containers, rockeries, and borders, and works especially well in Japanese- or woodland-inspired gardens.
