Sagittaria trifolia / Omodaka オモダカ

Sagittata trifolia is a perennial herb inhabiting shallow marshes or wetlands, extending runners underground to make small corms at the ends. Leaves are rooted; young plants' leaves are linear and in the water; generally, however, they have long pedicles and are erect to get out of water. Blades are sagittate, with bases split into two lobes, 7-15cm in length; either of the two lobes is longer than the terminal ones and tips sharply pointed. Flower stems grow to 20-80cm tall and set three white flowers, 1.5-2cm across, in a whorl on each node; male flowers come on the upper parts of the flower stalks, and females on lower portions. Bloom time: August-October.
