Marsilea mutica (Four Leaf Water Clover) is a charming aquatic plant forming a mat of floating four-leaf clovers, 1-3 in. (2-7 cm), adorned with reddish-brown arching stripes. Although it looks like a four-leaf clover, Marsilea mutica is actually an aquatic fern. Very cold hardy, Four Leaf Water Clover is a fast grower and a good plant to help cover the water surface. However, it spreads vigorously by rhizomes and can be highly aggressive. To manage its spread, plant in a 1-gallon container.
