Zijin Grass
During the War of Resistance against Japanese Aggression (1937-45), a Japanese army doctor named Yamaguchi Seitarou (Chinese: 山口诚太郎; Japanese: 山口 誠太郎/やまぐち せいたろう) was deployed to Nanjing, East China's Jiangsu province. When he left the ruined city in 1939, he collected a handful of seeds of a local purple flower blossoming at the foot of Zijin Mountain and brought them back to Japan. He named the flower Zijin Grass, also known as Chinese violet cress and February orchid.
