Water Stargrass
Water stargrass obviously derived its name from its conspicuous, pale-yellow, starshaped flower that protrudes above the water's surface when in bloom. Also known as mud plantain, water stargrass has small, linear leaves 2 to 4 inches long and less than 1 / 4 inch wide. The plant is a perennial usually firmly rooted in the sediment and, when given the opportunity, can develop into dense, but patchy beds.
