The Story
Potamogeton nodosus (Longleaf Pondweed or Knotty Pondweed) is a fully aquatic, perennial plant native to Texas and much of North America. With long, ribbon-like floating leaves and slender flower spikes that rise above the water's surface, it plays a key role in freshwater ecosystems. Often used as an oxygenator in water gardens and natural ponds, this submerged-rooting plant thrives in full sun to part shade and helps provide habitat and cover for aquatic life. Its high deer resistance and water-purifying benefits make it ideal for ecological pondscapes.

Origin: Texas and North America
Native Habitat: Shallow to deep freshwater ponds, lakes, and slow streams
