Argument When Japan faced the world after the collapse of its feudal system, it had to invent its own modern identity in which the Tokyo Cherry became the National Flower. Despite being a garden plant, it received a Latin scientific species name as if it was an endemic species. After Japan’s colonial conquest of Korea, exploring the flora of the peninsula became part of imperial knowledge practices of Japan. In the wild, a different cherry was discovered in Korea that was (...) proposed as the endemic parent of the Tokyo Cherry, supporting imperialist policies. Following Japan’s defeat after the Pacific War, South Korea in turn entered its search for cultural identity. The supposed parent of the Tokyo Cherry was now successfully acclaimed as the parent species of the colonial oppressor’s Tokyo Cherry and named the King Cherry. Such scientific practice into cherries smoothly intertwined with nationalism and its legacy continues to interfere with research today. (shrink)
