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.

Allium triquetrum - Three-cornered Leek

A very common sight in West Cornwall and on the Isles of Scilly during the spring, Allium triquetrum grows along road verges and banks, and at the base of hedges. It can also be found on Head cliffs and in the cliff-top sward, often interspersed with bluebells. Stinking Onions, as they are known locally, are noticeably more common on main roads than minor roads, suggesting that the movement of traffic may influence its dispersal, but ants are also involved in its spread.
