A winter-annual of grassland habitats on dry, relatively infertile neutral or base-rich soils, and thus more demanding and less frequent than T. dubium. It also occurs on spoil heaps from slate and limestone quarries. 0-350 m (Minninglow, Derbys.).
T. campestre was mapped as `all records` in the 1962 Atlas. The timing and causes of its apparent decline across parts of the north and west of its range are unclear.
Eurosiberian Southern-temperate element; widely naturalised outside its native range.
