Sagittaria trifolia is
a perennial herb that inhabits shallow marshes or wetlands, with
runners that extend underground to form 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 the water. Blades are sagittate, with bases split into two lobes,
7-15cm long; either lobe is longer than the terminal ones, and tips
have sharp points. 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. |
