  Best Time to Search

The phenology of J. subtilis in Minnesota is poorly known. It is likely dependent on lake levels, which can vary from month to month and year to year. Taking this uncertainty into account, the best time to search for J. subtilis is likely July through early September. Years with below normal lake levels may expose more shoreline habitat, making access easier and improving chances of finding plants.
