Curly-leaf Pondweed
Curly-leaf pondweed is a submerged perennial that resembles many native pondweeds. Care must be taken to correctly identify this species. Rigid, reddish-green, oblong leaves have distinct, finely toothed, wavy edges. The plant’s flat, reddish-brown stem grows from one to 16 feet. Most reproduction is from winter buds, called turions.
