Ludwigia palustris is a perennial aquatic plant commonly found in wetlands, marshes, and along the edges of ponds and streams. It features elongated, lance-shaped leaves that can grow up to 10 centimeters long. The plant produces bright yellow flowers, typically blooming from late spring to early summer, which attract various pollinators. This species is known for its ability to thrive in both submerged and emergent conditions, making it adaptable to different water levels. Ludwigia palustris plays a vital role in its ecosystem by providing habitat for wildlife and helping to stabilize soil in wetland areas.
