Japanese iris, or iris ensata as they are also known, are the rare exception to the “plant in well-drained soil” sermon that you often hear preached. These plants do well with wet feet, in somewhat boggy sites and along the edge of a pond where their breezy beauty is doubled by their reflection. No available bog? Pot up your Japanese iris bulbs and submerge them in a tub, water feature or galvanized trough. Or commandeer that bare spot next to where the side spigot drips. These irises are worth creating a site for . . . really.
