Brasenia schreberi, also known as water-shields, grow in areas near Mao Lake and the "nine hills". They often grow in the wild and are considered the best of the aquatic vegetables. The history of eating brasenia schreberi can be dated back to the Western Jin Dynasty (265-316). In modern times, brasenia schreberi are on the verge of extinction. With the assistance of the science and technology committee of Songjiang district, areas near Xiaokunshan town have begun to cultivate the vegetable.
