Plants in genus salvinia
Salvinia minima
Salvinia minima is a fast-growing aquatic fern native to South America, Mesoamerica, and the West Indies. It forms dense mats on the surface of still or slow-moving freshwater, providing habitat for froglets. This plant is invasive in many regions, including parts of the United States, and can outcompete native species. It reproduces asexually and requires management to prevent ecological disruption.
Salvinia cucullata
Salvinia cucullata is a small aquatic fern with nickel-sized leaves that can form thick mats. It is suitable for low-tech aquariums and paludariums, providing shade to prevent algae growth. This floating plant grows quickly and is ideal for small fish.
Salvinia natans
Salvinia natans, commonly known as Floating Fern or Water Butterfly Wing, is an annual aquatic fern native to Africa, Asia, central Europe, and South America. It features two floating leaves and a submerged leaf that functions as a root, with air pouches for flotation. This plant forms thick mats that can cover entire ponds or lakes, providing shade and reducing algae growth. It is suitable for low-tech aquariums and paludariums, thriving in partial shade with a fast growth rate.
