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.

Archaeophyte. Perhaps originated in the Mediterranean region and South-west Asia.
Scattered across Britain and Ireland with few modern records.
A very rare casual, mostly associated with waste disposal sites in recent decades, apart from one 1992 record near the Upper Tamar Lake where it grew in a flax field (SS21).
Habitat & Ecology
Waste places and arable field.
