Azalea mollis 'Koster’s Brilliant Red'
Azalea mollis 'Koster’s Brilliant Red', also listed as Rhododendron molle hybrid, is a striking deciduous azalea grown for its vivid floral display. In late spring, it produces large trusses of trumpet-shaped, brilliant scarlet-red flowers that stand out dramatically against the fresh green foliage. These vibrant blooms are lightly fragrant and attract pollinators, adding both colour and life to the garden.
As the seasons turn, the foliage provides further interest, shifting from green to rich autumn shades of orange, yellow, and red before falling. Compact and bushy in habit, this variety thrives in acidic, moist but well-drained soil and performs best in partial shade. Perfect for woodland planting, mixed borders, or as a bold specimen shrub, ‘Koster’s Brilliant Red’ delivers a powerful splash of seasonal colour.
