Flora of Cornwall (1999)

The descriptive text, below the map, is from the Flora of Cornwall (1999), which was a Tetrad Atlas (the maps had 2km square dots or Tetrads). The map on this web page depicts the plant's distribution at the 1km square scale and shows the records made pre-2000 which were used in the 1999 Flora and those made since.

Cirsium arvense - Creeping Thistle



Creeping Thistle is a very common agricultural weed in Cornwall and the Isles of Scilly, which is able to tolerate a wide range of habitats and soil conditions within the farming environment. Its frequency has, however, become noticeably reduced since the advent of selective herbicides.
