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.

Polygonum aviculare - Knotgrass



Knotgrass is a very common and widespread plant in Cornwall and the Isles of Scilly. It occurs in waste places, on road verges, in gardens and as an agricultural weed.
