It is a frost tender annual in colder areas or if placed in shaded area in the garden, but can be kept as a perennial if it is well managed and placed in full sun during the winter. Morning glories in Japan Morning glories are popular in Japan. They are believed to have been introduced there directly from China in the Heian period of the 8th to 9th centuries. During the Edo period of the 17th to 19th centuries, as more people started to live in cities, a fad for growing potted morning glories of different colors and sizes swept through the country. The pots are often equipped with cylindrical structures called andon shitate'' (), which look like Japanese lanterns at night. In early summer, morning glory markets are held in large cities in Japan, where merchants and hobbyists sell the flowers. The largest of such markets is the Iriya Morning Glory Market (Japanese: 入谷朝顔市, July 6–8), held along the roads surrounding Shingenji Temple, commonly called "Iriya Kishibojin", in Iriya, Taito-ku, Tokyo.
