Everything's coming up roses in Jiangsu

Tang Jing sells yellow "roses", wrapping them in bunches in green paper and colorful ribbons. If you don't look closely, you may not notice that they are actually cabbages.

Such cabbages have been popular gifts in Jiangsu province since they appeared on the market before Spring Festival, which began shortly after Valentine's Day this year. Each cabbage sells for 8 to 10 yuan ($1.30-1.60).

Tang, the manager of Kunshan Yuye Vegetable Planting Base, which is supervised by Nanjing Agricultural University, said the "roses" can be purchased only in winter because they take on their beautiful bright yellow color only during cold days.
