A biennial garden plant grown for its red-purple (rarely white) flowers and the large almost circular flat fruits whose central translucent septum persists for months on the dead stems and are used in flower arrangements. It is not native to Ireland, but occurs occasionally on rubbish dumps - the product of dumped garden waste.
All names: Lunaria annua L.
