Flame Azalea (Rhododendron calendulaceum) is a striking deciduous shrub, lending a burst of fiery color to your garden. Native to the Appalachian Mountains, this elegant shrub matures to a height of 4-8 feet and spreads 8-10 feet, proving ideal for garden landscapes from Pennsylvania to Georgia. Flame Azalea captivates with its large, funnel-shaped flowers, varying from orange to yellow to red, blooming from late spring to mid-summer. These nectar-rich blossoms are a haven for pollinators like butterflies, bees, and hummingbirds.

This resilient shrub thrives in acidic, well-drained soils with partial shade, smoothly adapting to moist, loamy, or sandy grounds. It’s a low-maintenance plant, perfectly suited for hedges, shrub borders, or naturalized areas. Despite its beauty, it withstands rabbit browsing and prefers cooler summer conditions, making it suitable for hardiness zones 5-7. The fall foliage metamorphoses into stunning red and burgundy shades, while its unique gray-brown bark provides winter interest. Enhance your landscape with this spectacular native shrub, fostering biodiversity and delighting with its vibrant display.
