Georgia designated azalea as the official state wild flower in 1979 (the state flower is the Cherokee rose). Blooming from March through August, these dazzling wild flowers range in color from white to yellow, orange, scarlet, crimson, and intermediate shades and blotches.

No specific variety was selected to represent Georgia, but several native varieties are mentioned in the resolution as occuring in every county of the state (including Rhododendron Austrinum, prunifolium, canescens, alabamense, calendulaceum, speciosum, arborescens, and serrulatum).
