Common plant of woodland glades

Observation - Common plant of woodland glades - UK and Ireland. Description: This is a common plant of woodland glades, growing eg on muddy paths where there is a gap in the tree canopy. But what is it? I saw it here on sandy soils, but I have a feeling I have seen it often elsewhere
