Potamogeton foliosus subsp. fibrillosus, commonly known as Leafy Pondweed, is an aquatic perennial herb native to a wide range of freshwater habitats across North America, including lakes, ponds, and slowly-moving streams. It thrives in submerged conditions, often forming dense mats beneath the water’s surface. Leafy Pondweed typically prefers full sun but can tolerate partial shade, contributing significantly to the health of aquatic ecosystems by producing oxygen and providing habitat for aquatic wildlife.

Leafy Pondweed is valued for its ecological role in water bodies, aiding in water purification and serving as a food source for waterfowl and habitat for fish. It is not commonly used in traditional gardening but is important in the management of natural water features and in the creation of wildlife-friendly environments. In cultivation, it requires an aquatic setting with clear, shallow water and can spread quickly under ideal conditions. While generally low-maintenance, it can become invasive in some areas, outcompeting native species and potentially clogging waterways.CC BY-SA 4.0
