Cosmos, also called Mexican Aster, is an easygoing garden favorite that blooms its heart out from summer into fall. Airy foliage and daisy-like flowers in bright pinks, whites, purples, and rich reds float on tall stems, adding a light, meadowy feel to beds and borders. Cosmos loves full sun, handles heat well, and keeps flowering—especially when you deadhead or cut for bouquets. Pollinators adore it, too, making it a simple way to bring butterflies and bees to your garden. Shop Annie's Annuals & Perennials Cosmos here!
