Iris reticulata? Assuming they still have leaves, remove them intact with as much root as possible and replant them into a pot. Give them a feed and keep them watered as needed until the leaves die down naturally. At that point you can stop watering and leave the pot somewhere sheltered and out of the way (eg under a bush.) Bring it out next spring, water it and, with luck they'll flower again. They aren't completely hardy in parts of the UK so there's always a chance you'll not see them again.
