This species is the most closely related to Ipomoea nil. Having originated in tropical portions of the Americas, Ipomoea hederacea is now distributed in many parts of the world. It was introduced into Japan in the Meiji era, but it became naturalized still more once it entered the country with cereals supplied by the United States during the post-World War II food shortage. Now it is settled in wide regions of Japan. The leaf is three-pointed, but the interval part of leaf lobes is curved (Hederacea leaf). Other characteristics include a small, light blue flower and sepals that spread to the outside. There is a round leaf type, too.
