One of the most generous bloomers in the perennial garden, Totally Tangerine sends up a long succession of warm, glowing tangerine-orange flowers on slender, wiry stems from early summer into fall. The blooms float airily above a low, tidy mound of soft green foliage, creating a see-through layer of color that mixes effortlessly with roses, salvias, and ornamental grasses. Remarkably free-flowering, it simply keeps going — especially if you snip the spent stems — and the cheerful blooms are lovely in a cutting bouquet. It thrives in full sun with average moisture and is refreshingly trouble-free, untroubled by deer, rabbits, or pests. Butterflies are regular guests at the nectar-rich flowers. For months of sunset color and easy charm, few perennials work as hard.
