The visible leaves of many (if not all) Potamogeton species die in the autumn but the plant regrows from the rhizome in the spring.
P. crispus is an invasive species that clogs many waterways in northern USA. I have caught it and its partner in crime, Eurasian millfoil, many times while fishing in bays of Lake Ontario.
