Students from Nanjing Agricultural University harvest a special breed of cabbage dubbed “yellow rose” on a farm in Nanjing, Jiangsu province, on Monday. Named for its resemblance to a rose with green leaves surrounding a yellow heart, the cabbage is a new variety developed by Nanjing Agricultural University over a period of 18 years. It is rich in nutritional value, with over three times the vitamin C content of other cabbages and six times the calcium content of milk.
