Rhododendron ‘Blue Danube’ | Blue Danube Azalea

$0.00

DESCRIPTION
Rhododendron ‘Blue Danube’ is a compact evergreen azalea with glossy, medium-green leaves that often take on a subtle bronze cast in winter. In mid-spring it becomes covered in dome-shaped trusses of broadly funnel-shaped flowers. The blooms are violet to violet-blue, often with red spotting at the throat.

This cultivar has earned the Royal Horticultural Society Award of Garden Merit for its reliable flowering and garden performance. Its compact habit, dense evergreen foliage, and cool-toned spring blooms make it a good candidate for mixed borders, woodland plantings, or container cultivation where its spring color and structure can be enjoyed close to pathways or entrances.
