A procumbent perennial herb, rooting at the nodes. On the coast it is found behind saltmarshes, on earthen sea-walls and grazing marshes. Inland it occurs in pastures or by tracks on damp alluvial or calcareous clay soils. It sometimes grows in long-established amenity grassland or lawns. Lowland.
The distribution of T. fragiferum shows declines in some areas, largely due to the improvement of old pastures or their conversion to arable, although such losses do not always show at the 10-km scale (e.g. in Dorset). It is still frequent in its coastal habitats, despite the extensive draining and ploughing of grazing marshes.
Eurosiberian Southern-temperate element; widely naturalised outside its native range.
