That's garlic mustard, Alliaria petiolata. If it's in the way, it's a weed... otherwise it's a wild flower, an important food plant for the caterpillars of orange tip butterflies.
Since 2019 I've lived in east Clare, in the west of Ireland.
@Liriodendron@Buttercupdays ah lovely, thanks! I will leave it for the butterfly’s or at least some as there’s loads of it! 😊 I’m guessing it’s not for human consumption!?
