Grow Flame Azalea (Azalea calendulaceum) for a bold late-spring show of funnel-shaped blooms in yellow, orange, and red tones. This deciduous shrub typically reaches about 4-8 feet tall and 8-10 feet wide, making it a strong specimen or a natural choice for shrub borders and open woodland gardens.
Site it in part shade to shade for best performance, especially where it is protected from harsh afternoon sun. In brighter exposure, leaves can scorch unless you keep moisture steady. Plant in moist, well-drained, acidic soil with plenty of organic matter; avoid poorly drained sites and heavy clay unless you amend and improve drainage. Mulch with bark, wood chips, or pine needles to help keep roots cool and evenly moist.
After flowering, prune lightly as needed, since next season's buds form by mid to late summer. Flowers provide nectar for pollinators, including butterflies and hummingbirds. Like many azaleas, it can be prone to insect and disease issues if stressed, so focus on the right site, good drainage, and consistent care.
