Azalea ‘Avondgloed’ – Brilliant Orange-Red Knaphill Azalea for Spring Colour
Azalea ‘Avondgloed’ is a striking Knaphill azalea, producing clusters of vivid orange-red trumpet-shaped flowers in late spring. The intense colour creates a dramatic burst of warmth in the garden, standing out beautifully against the fresh green foliage as the shrub comes into bloom.
The flowers appear in generous clusters along the branches, creating a rich and eye-catching display. Planted in groups or combined with other azaleas and rhododendrons, ‘Avondgloed’ provides a spectacular highlight within woodland-style borders.
With its naturally bushy, upright habit, this variety works beautifully as a specimen shrub or within mixed borders where strong spring colour is desired. It pairs especially well with ferns, hostas, and other shade-loving plants that complement its woodland character.
Like other Knaphill azaleas, ‘Avondgloed’ thrives in partial shade and prefers acidic, well-drained soil enriched with organic matter. Once established, it is hardy and reliable, requiring little maintenance beyond occasional shaping after flowering.
Vibrant, dramatic, and wonderfully dependable, Azalea ‘Avondgloed’ is an excellent choice for gardeners looking to introduce bold late spring colour.
