Is this American Water willow in the pictures below?
Amercian Water Willow I have regular willows that I control, but this is the first I have seen of this. I have two small plots of a few plants each. Both are beside some spike rush. I wonder if it has come in from birds.
Don't know if I should try to kill it out while it is small and a small amount, or if it is desirable and let it grow.
First I need to ID it for sure. The background stuff with the purplish leaves is water primrose. I know what it is. It is the upright green plant I am interested in. Pics below.
