Commonly referred to as Large Leaf Pondweed or Broad-Leaved Pondweed. It produces a very slender, cylindrical, sometimes spotted stem up to four feet long. The leaves take two forms. Submersed leaves are 7″ long and 2″ wide and may be folded. Floating leaves are about 4-5″ long and 1″ wide and leathery in texture.
One plant can send out many leaves that float on the surface. Water beads off of the waxy cuticle of the leaf. Floating leaves provide shelter and habitat for fish.
If the plant reaches nuisance levels control can be achieved with aquatic herbicides.
