Square-stalked St. John's-wort Hypericum tetrapterum

Square-stalked St. John’s-wort grows happily in the damp roadside ditches near my home in Moyard, Connemara. The plant, with its pretty yellow flowers has a long history in herbal medicine, being used to treat depression. In Ireland, it is available only with a doctor’s prescription as it does have possible side effects.
