The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
Archaeophyte; Lowland, Eurosiberian southern-temperate species. Almost restricted to the southern half of the British Isles.
Found throughout Cornwall except in the St. Austell and Bodmin Moor granite areas and north-east Cornwall. Since 1999 it has been found in several dozen new sites. In Scilly it is scattered on arable land on the inhabited islands and occasionally on disturbed ground. It is possibly in decline.
Habitat & Ecology
An arable weed of corn and bulb-fields, horticultural crops and in allotments. It is very
rarely seen in gardens and waste places. It is normally only seen in small numbers.
Threatened by agricultural intensification and crop changes that do not accommodate spring-germinating weeds.
Many sites are not protected.
