A new and unique cultivar of garden phlox named Phlox ‘Fashionably Early Flamingo’ multi-stemmed, dense, slowly-spreading habit with bright-green, glossy, lanceolate leaves. Flowers are sweetly-fragrant, initially light lavender-pink flower faces becoming pale lavender with light purple eye zones beginning late spring, continuing for about five weeks and repeating through mid-fall. Foliage stays clean and resists mildew.
