Nipponanthemum nipponicum, commonly known as Nippon daisy or Montauk daisy, is a plant species native to coastal areas of Japan. It is cultivated as an ornamental plant in other regions, and has become naturalized as an escaped cultivated plant along seashores in New York and New Jersey. This species is the only member of the genus Nipponanthemum, and was formerly classified as part of the genus Chrysanthemum. Nipponanthemum nipponicum is a shrub that can reach up to 100 cm (40 inches) in height. Most of its alternate leaves grow clustered near the top of the stem. Its flower heads can grow up to 8 cm (3 inches) across, and are produced singly. The ray flowers of this species are white, while the disc flowers are usually yellow, and occasionally red or purple.
