Typha is a wild vegetable in China. It is called Typha latifolia as food. It is mainly eaten in three parts, one is the false stem with leaf sheath, the other is the underground grape stem, and then the shortened stem. After picking and cleaning, it looks like "water bamboo", very white and tender, fried or made into soup, and it tastes very delicious. In addition, the cattail stick is also a good snack when it just blooms. In the north of our country, many children will pick the cattail sticks that have just blossomed in the wild, peel off the soft skin and eat them in their hands.
