A perennial plant of the Convolvulaceae family (APG classification: Convolvulaceae). The stems grow in clusters on the ground, and the leaves are small and kidney-shaped.

It grows on roadsides and around houses in hilly areas, growing in the Kanto region and west of Honshu, Shikoku, Kyushu, and Okinawa, and is widely distributed in the subtropics and tropics of the world. The Japanese name comes from the fact that the leaves resemble those of Futaba Aoi and are short like moss. The genus Aoigoke has thin, creeping stems and small flowers. There are 14 species in the world, and all but Aoigoke are distributed in the tropics and subtropics of America.
