Not a flower but a fungus farmed on rice and other media: small orange-red clubs, golden when dried. It tastes like a mild mushroom and goes into soups. It is a different, far cheaper species than 冬虫夏草.
Mom simmered a pot of soup with cordyceps flowers and chicken.

Not the expensive wild 冬虫夏草 either: it is a related fungus, Cordyceps militaris, farmed on rice and other media. Its thin orange stalks go into chicken soup, pork-bone soup and hot pot.
