Azalea

Azalea is a familiar common name for a diverse group of flowering shrubs within the genus *Rhododendron*. The group includes evergreen and deciduous plants with varied sizes, flower forms, colors, and seasons of bloom. Because azaleas vary widely, choose by the named species or cultivar’s mature size, bloom period, and climate fit. ## Form and flowering Azaleas range from compact mounds to large shrubs. Most garden forms flower in spring, though [University of Georgia Extension](https://fieldreport.caes.uga.edu/publications/B670/selecting-and-growing-azaleas/) notes that selected types bloom in summer and fall as well. Evergreen kinds retain some leaves through winter; deciduous kinds drop them in autumn. Flowers may be single, double, or hose-in-hose, and colors vary by species and cultivar. ## Growing conditions Provide filtered light or partial shade where summers are hot, with acidic, organic-rich soil that drains freely but remains evenly moist. Azaleas have shallow roots, so they can show stress quickly when the root zone dries. A site with good drainage is essential; persistently saturated soil can injure roots. Extension recommendations vary with cultivar and region, which is why the catalog’s broad dimensions and zones are retained rather than narrowed to a particular type. ## Landscape use Use named cultivars when a planting needs a dependable mature size, flower color, or hardiness range. A mixed planting can extend seasonal bloom, while evergreen selections can contribute foliage structure between flowering periods. Check local adaptation before specifying a particular plant for an exposed or very cold site. ## Maintenance Refresh an organic mulch layer to conserve moisture and keep shallow roots cool. Check soil moisture during dry weather and water thoroughly when the root zone begins to dry, avoiding waterlogging. If pruning is needed, do it soon after flowering; spring-flowering azaleas set next year’s flower buds during summer. Avoid heavy feeding unless soil or plant symptoms indicate a need.
