Ipomoea purpurea also originated in the tropics of the Americas. It was introduced into France in 1629 (Guyot, L., Gibassier, P.). The flower is 5 to 6 cm in diameter, and the leaf is a round type. Because it opens many flowers and can bear fruit capsules in the lower temperatures of autumn, it has been cultivated in Europe and North America for a long time, and most gardening varieties have been brought up there. Though it was introduced into Japan under the name "Yatubusa" in the Fukuoka region around Kanei 7 (1630) (New Grand Gardening Dictionary 1969 vol. 4, p.2104, Seibundo-sinkousha), but the Flaked strain was imported in the middle period of the Meiji era (1868-1912) (Naganuma, 1903).

Genetic studies of Ipomoea purpurea were started mainly on the Flaked strain (Barker, 1917). In Japan, Imai (1927) found an intermediate heredity in red and white flower inheritance. It was recently reported that a transposon inserted in a pigment synthetic gene is related to the mechanism that provides the characteristic of a flaked appearance.
