To investigate and compare the variety of different flowers used in a painting of flowers and birds of Japan and Korea, the relevant Japanese era to Joseon Dynasty where traditional folk art revitalized was studied. This study aims to deliver a through and prescriptive approach to the research in question through horticulturalistic and color-orientated approach as well as the standard format of research and development. Through this study Japanese paintings were shown to prefer peony at best and other flowers such as Japanese apricot, Chrysanthemum, Bamboo, Japanese red pine were also popular which is similar to those of the Joseon period. However in Joseon dynasty, peony seized 17% of all flowers used in Folk-Art paintings unlike 10% in Japanese paintings. Whatsmore 10 of 20 most favoured plants of Joseon dynasty were shown to be shrubs whilst it was 6 for Japan illustrating flowering plants were more popular. The study of range showed paintings of Joseon dynasty using 85 varieties whilst Japanese paintings using 82 varieties hence again showing similarity. Moreover Joseon paintings illustrated that they used mostly wild flowers whilst Japanese paintings depicted more imported flowers such, Pyracantha, Gladiolus, Carnation In terms of identification of flower in the paintings, Japanese practiced precise painting technique making it easy to identify unlike the Joseon paintings where more abstract techniques of folk-Art producing difficulties in classification.
