Bolbitis heteroclita, commonly known as Asian Water Fern, is an evergreen fern native to the humid, shaded stream banks and marshy areas in tropical and subtropical regions of Asia, extending to the Caroline Islands. It typically grows to a height of 0.5-1 feet (0.2-0.3 meters) and can spread widely, with a width of 6-12 feet (1.8-3.7 meters). The fern has delicate, pinnate fronds that resemble those of poison ivy but are harmless. The fronds are bright green and can add a lush, tropical feel to a garden setting or aquarium.

Asian Water Fern is valued for its adaptability to aquatic environments, making it a popular choice for garden ponds and freshwater aquariums. It thrives in full shade and requires high humidity or aquatic conditions, with soils that provide slow or standing drainage. While it can be challenging to grow fully submerged, Bolbitis heteroclita is easier to cultivate as a terrestrial or emersed plant in ponds. It is often used as a decorative element due to its attractive foliage and ease of maintenance when grown in suitable conditions. Gardeners should be aware that this species may be sensitive to changes in water quality and temperature.CC BY-SA 4.0
