“THE MUTANT MORNING GLORY (“asagao”) has been a cherished flower since the days of old. Japan experienced repeated morning glory booms, particularly starting in the late Edo era (the imperial eras Bunka, Bunsei, Kaei, and Ansei (1804-1830,1854-1860)) and on into the Meiji and Taisho eras. A great many varieties were created around the end of the Edo period.””
