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.

Hypericum humifusum - Trailing St John's-wort

Trailing St. John' s-wort grows on hedgebanks, heaths, waste ground and woodland banks, in rather open conditions and often where conditions are acid and the soil stony. It is believed to be a species that is still spreading its range where suitable habitats exist and is increasingly being found in maize stubbles.
