The beautiful black waters of Swan Lake form the setting for the spectacular Iris Gardens. The lake is dotted with colorful islands, and wildlife is abundant. The only public park in the United States to feature all eight swan species, Swan Lake-Iris Gardens 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 also boasts many other floral attractions, including colorful camellias, azaleas, day lilies, and Japanese magnolias. A Braille Trail enables the sight-impaired to enjoy the scents and sensations of the gardens. The gardens come alive with color during the Christmas season with the nighttime Fantasy of Lights display, featuring more than 1,000,000 varicolored sparkling lights in an array of colors and shapes.
