Thanks, I have 3 irises too, two mauve and one yellow I think. Soapwort is poisonous, isn't it?Don't know about poisonous. We don't eat it ;D.Its a delicate little plant with pink sweet smelling flowers. Apparently there are several species.
Water cress is a good idea, it's not something I've bought so will have to see if it's available locally.
