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.

Sempervivum tectorum - House-leek



House-leek was once planted on house roofs in Cornwall in the belief that it protected the houses from lightning strikes. The only recent record is from a disused farm building at Higher Beeny (SX19B, 1993, C.N.French).
