Potamogeton amplifolius

Largeleaf pondweed is a native plant species to Connecticut. A native plant is one that occurs naturally in a particular habitat, ecosystem or region without human introduction. It is well adapted to that region’s soil, moisture and weather conditions. Largeleaf pondweed is a common freshwater plant that can grow to burdensome abundance when conditions are ideal. Its leaves are larger and have more veins than any other pondweed (Potamogeton) species, and it often grows in somewhat deeper water. Leaves may float at the surface or be submerged underwater. The leaf is not divided, rather the blade is made up of one segment that measures 43 to 125 mm in length, and 15 to 58 mm in width.
