General Comments:

The range of this plant appears to encompass most of Florida with actual occurrances having been found in streams with appropriate water chemistry (appears to like relatively neutral pH and high nutrients).  Has been planted in areas where it is not known to occur naturally including old mine ponds and reclaimation areas.  

This plant is not a nuisance in Florida.  It is, however, listed as a nuisance invasive in Australia.
