Swan Lake Iris Gardens is the only public park in the United States containing all eight known species of swan. The lake is dotted with islands and wildlife. The park is also home to some of the nation's most intensive plantings of Japanese Iris, which bloom yearly in mid to late May and last until the beginning of June. The garden is also planted with camellias, azaleas, day lilies, and Japanese magnolias. A Braille Trail enables the sight-impaired to enjoy the scents and sensations of the gardens.
