Range & Status
Archaeophyte; European Temperate species. Mainly eastern England, especially East Anglia and in chalk areas. A few sites in Ireland.
Always been very rare in Cornwall. Only currently known from three 1km squares, at West Pentire (SW76), north of Porthtowan (SW64) and Two Burrows (SW74), but has occurred in 38.
Habitat & Ecology
Usually found in arable fields, on light, sandy soils, near the coast. Sometimes occurs as a casual on waste ground.
Intensive arable farming, and ironically, at its Porthtowan site, heathland recreation!
It is protected at West Pentire, where the arable fields are actively managed to maintain a diverse arable weed flora, by the National Trust, and part of the heathland recreation site north of Porthtowan, also owned by the National Trust, has been maintained as an arable field.
