Bill -
The plant in my hand is the same as the plant "under water". In water 3.5' or less the plants seem to be strong enough to stand upright out of the water, but when the water is 4' and deeper the plants don't seem to be able to stand upright out of the water but fall over.
I will pull out one of each when I get another opportunity but I am 99.9% certain they are the same. I could be wrong though. .01% chance
All these grass looking plants start at the bottom and grow upright through the Spring and Summer. Looking at the Sweet Flag I know that I have never seen the flower that is cone like in appearance for the pictures I've looked up. So I am uncertain about that?
