These are water iris and need more moisture than bearded and even more than some other beardless. If you have a pond put in a pot and stick it in the pond (shelf is best). If not pot in a pot (BIG) and solid and plant in the ground. These are very evasive and should not be near a natural water way and in many states they are considered a noxious weed.

Except that I am hosting a cultivar of I. Pseudocorus I would not have it one my property with out precautions.
The picture is of I pseudocorus growing in the back wash of the Toutle River which is the river that was destroyed during the Mt St. Helen's erruption. the other noxious weed growing with it is skunk cabbage
