Allium triquetrum (Three-cornered leek)

The image features Allium triquetrum, commonly known as the three-cornered leek or three-cornered garlic. This bulbous perennial is easily identified by its white, bell-shaped flowers that droop in clusters and feature a distinct green stripe on each of the six petals. Its name refers to the triangular cross-section of its flower stalks. While it is often mistaken for snowdrops (Galanthus) or white bluebells, its strong onion or garlic scent when crushed is a definitive identifier.

Originally native to the Mediterranean basin, including southwestern Europe and northwestern Africa, the plant has naturalized across many parts of the world, including the United Kingdom, Ireland, Australia, and New Zealand. In several of these regions, it is classified as an invasive weed due to its ability to spread rapidly through bulb offsets and seed dispersal.

All parts of the three-cornered leek are edible, offering a flavor profile similar to garlic or spring onions. It is frequently foraged for use in salads, pestos, and soups. However, gardeners and foragers should be aware that in certain countries, such as the UK, it is legally restricted under environmental acts (like Schedule 9 of the Wildlife and Countryside Act) which prohibit its intentional introduction into the wild.
