These versatile perennials shine in a variety of garden settings--from native and pollinator gardens, to naturalized areas, to meadows and mixed perennial flower beds. Coneflowers are sun-loving perennials and will grow in full sun to partial shade. Plant coneflowers where they will receive at least 4 hours of direct sunlight daily. When buying echinacea plants, pay attention to the variety's height. Some coneflowers may grow 18 inches tall while others grow 3-4 feet. Coneflowers should be spaced about 18-24 inches apart.
