Pond plants particularly taller Iris types (Flintshire CH1)

Hi. We're building a pond with some good sized boggy areas to the sides that we need to get planted out. If anyone is thinning out or clearing any marginal/bog/marsh plants then I'd be happy to give them a new home. I'm particularly looking for clumps of taller Iris type plants to build a marshy area. Happy to take directly out of your pond if you don't want to get wet!!
