Garden Rainbow Azalea (Rhododendron ‘Garden Rainbow’) delivers a radiant color show in late spring when its sunny yellow flowers gradually turn orange and then pink. These tricolor blooms unfold in early June, creating a spectacular rainbow effect that draws attention to any landscape. The upright, deciduous habit reaches about four to five feet tall and three to four feet wide, making it a striking accent or backdrop in garden beds. Mildew-resistant foliage adds further appeal by staying fresh and green well after the flowers fade. This versatile selection shines as a single specimen or in groupings along wood lines and borders.

Large trumpet-shaped blossoms attract butterflies, hummingbirds, and other pollinators, transforming your garden into a lively haven for wildlife. Native to regions with moderate climates, Garden Rainbow Azalea grows best in Zones 5 to 8, tolerating varied conditions while delivering steady performance. Its wide, upright form also fits well into woodland gardens, cottage borders, and mixed shrub plantings. Consider showcasing it in semi-shaded areas for a beautiful, natural look that still brings dramatic splashes of color.

Garden Rainbow Azalea Care

Plant this azalea in acidic soil with good drainage, making sure the location receives partial sun or filtered light. Amend the planting area with organic matter if your soil requires improved fertility or drainage. Water routinely to keep the soil consistently moist, especially during active growth and flowering, but avoid waterlogged conditions. A slow-release, acid-specific fertilizer applied in early spring gives the shrub a nutrient boost. A light layer of mulch around the base helps conserve moisture and maintain a comfortable soil temperature.

Pruning typically takes place right after flowering, removing spent blooms and shaping the plant if necessary. Thinning out crowded branches improves airflow and reduces the likelihood of fungal issues. Consider light pinching or trimming to maintain a tidy shape, especially if grown in containers. In colder climates, a protective layer of mulch around the root zone may benefit the plant through winter.

Garden Rainbow Azalea Spacing

Allow about three feet between each shrub if planting a hedge or grouping for a consistent look. For a more open design or to maintain space between plants, place them five to seven feet apart. In container arrangements, pick a pot at least 12 to 16 inches wide with adequate drainage for the root system. Adjust the container size or spacing as the azalea matures, ensuring it has room to showcase its colorful blooms.
