A native of cool moist woods, twinflower often grows into large mats forming a beautiful ground cover. Bright green, glossy, evergreen leaves are borne in pairs on slender woody stems that may extend three feet in length. Delicate pink to white nodding flowers are fragrant and last about a week. They are produced in pairs on slender stalks in summer giving the plant its common name. The generic name refers to Carl Linnaeus a botanist known as the father of taxonomy. He chose twinflower as his personal emblem and had his portrait painted holding a twinflower plant.
