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.

Brassica nigra - Black Mustard



Black Mustard is a locally frequent and widespread plant along road verges, waste places, fly-tipping areas, on hedgebanks and on disturbed soil, especially along the coast. It is rare on the Isles of Scilly, and is absent from much of East Cornwall.
