Product Description
The Azalea japonica 'Blauwe Donnau'—also known as Rhododendron ‘Blue Danube’—is a highly decorative evergreen azalea prized for its vivid violet-blue blooms. Each flower, around 4cm wide, features a pale centre that creates an eye-catching contrast and enhances the overall floral display. The plant’s compact habit and oblong, dull green leaves offer year-round structure, making it a versatile choice for both small and larger garden spaces.
This azalea thrives in acidic, moist but well-drained soils and performs beautifully in partial shade or full sun, provided the position is sheltered. With an ultimate height of 1.5–2.5m and a spread of up to 1.5m, it is ideal for woodland-style planting, mixed borders, or as a statement container shrub. Its hardy nature ensures it withstands UK winters, offering consistent performance over many years.
Whether you want to introduce a splash of cool-toned colour, complement existing rhododendrons, or add seasonal interest to shaded garden corners, ‘Blauwe Donnau’ is an excellent and reliable choice.
