According to the "Flora of China" query, Chinese flowering cabbage is only used for ornamental or reserved as seeds, and can continue to be planted and collected.

There is a great difference in appearance between late cabbage and ordinary cabbage. Ordinary Chinese cabbage is very small, but it can even grow to more than one person. Because the late flowering Chinese cabbage didn't start sowing until the winter solstice, and it couldn't be harvested until 90- 120 days, which was later than ordinary flowering Chinese cabbage, so it got this vivid name: late flowering Chinese cabbage.
