Arrowhead

There are many species of Arrowhead (Sagittaria spp.) and all have arrowhead-shaped leaves with 3 points. The plant has several thick stalks with a single terminal leaf on each. The leaves grow in clusters from the base and can be from less than a foot tall to over 4 feet. The leaves have many uniform veins originating from the center and curving toward the leaf margin. Flowers are on separate stalks above the water in whorls of three and are usually white to light pink with three petals. Arrowhead usually lives in moist soil or very shallow water.
