| Sagittaria sagittifolia L. |
Sagittaria sagittifolia (also called arrowhead due to the shape of its leaves) is a flowering plant in the family Alismataceae, native to wetlands throughout the temperate regions of Europe and Asia.
It is a herbaceous perennial plant, growing in water from 10-50 cm deep. The leaves above water are arrowhead-shaped, the leaf blade 15-25 cm long and 10-22 cm broad, on a long petiole holding the leaf up to 45 cm above water level. The plant also has narrow linear submerged leaves, up to 80 cm long and 2 cm broad. The flowers are 2-2.5 cm broad, with three small sepals and three white petals, and numerous purple stamens.
[edit] Cultivation and uses
The round tuber is edible. In China, it is known as ci gu (慈菇, lit. "benevolent mushroom"), and its tuber is eaten particularly on the Chinese New Year. It tastes bland, with a starchy texture, similar to a potato but somewhat crunchier, even when cooked.
