This submersed plant is rooted. Common waterweed occurs in streams, ponds, springs, and lakes.

The slender stems of Egeria are usually a foot or two long, but can be much longer. The small leaves are strap-shaped, about one inch long and 1/4 inch wide. The leaf margins have very fine saw teeth that require a magnifying lens to see. Leaves occur in whorls of three to six around the stem. The flowers are on short stalks about one inch above the water. Flowers have three white petals and are about 3/4 inch across.
