Yellow Iris by the pond

Hi I`m sure this is the same Iris I planted in my newly formed pond in February this year, as soon as I planted it there was a very hard frost and the pond froze over and I was sure it would die, but it lived to tell the tale! The name of the Iris is IRIS PSEUDACORUS

love this Iris!The anglosaxons loved it, which shows how long it has been native to Britain.I want some flag iris if i ever have a pond as marginal planting! The yellow petals are beautifully coloured and textured with stripes the one I saw!
