Trillium grandiflorum blooms snowy white, but the flowers turn pink as they fade with age. Great Smoky Mountains National Park is a world-renowned preserve of wildflower diversity—over 1,500 kinds of flowering plants are found in the park, more than in any other North American national park. You can see where to find many of these flowers on the Species Mapper. In fact, the park is sometimes referred to as the “Wildflower National Park.” From the earliest hepaticas and spring-beauties in the late winter to the last asters in the late fall, blooming flowers can be found year-round in the park.
