This non-native, invasive, submersed plant, curly pondweed (Potamogeton
crispus),
was introduced from Europe more than 100 years ago and is now widespread in the U.S. It
occurs in all sstates (except Maine and South Carolina) and in southern Canada. In more
northerly climes where it is particularly weedy, curly pondweed actively grows under ice and
snow; is often the first plant to emerge in the spring; forms dense floating mats; flowers in June;
and dies and "drops out" long before the end of summer. This difficult-to-control aquatic weed
is relatively easy to identify -- it is the only pondweed with toothed leaves.
Potamogeton crispus is an invasive non-native plant to be
controlled.
