A winter-annual occurring in short, open communities around rock outcrops and on thin, relatively infertile drought-prone soils. Habitats include well-drained pastures, grassy banks and road verges. Although often growing in acidic sites, it is also found on base-rich neutral or even highly calcareous soils. 0-320 m (Derbys.).
Since the 1962 Atlas, some sites of T. striatum have been lost owing to the improvement or abandonment of pastures and other developments.
