Three Cornered Leek History

Three cornered leeks have been cultivated in Britain since 1759. An invasive species, three cornered Leek was brought over to the UK from the Mediterranean. It is a member of the allium family and originates from the Mediterranean, Madeira, Canary Islands and North Africa.The Three Cornered Leek is sometimes mistaken for white flowered Bluebells, but this inaccuracy can be quickly determined by the garlicky, onion smell of the Three Cornered Leek.

Where does Three Cornered Leek Grow?

Since Three Cornered Leek arrived in the UK it has quickly colonised grass verges, waste grounds, woods, hedgerows and gardens. Classed as an Invasive species, it is actually a criminal offence to introduce this plant to the wild in the UK.

Meaning, any intentional planting of Three Cornered Leek Bulbs in wild areas is subject to prosecution under schedule 9 of the Wildlife and Countryside Act. How does Three Cornered Leek Spread ? Three Cornered Leek is mainly spread through dispersal of seeds. Once established the Three Cornered leek plant forms dense clumps of growth.

Three Cornered Leek Identification

Three Cornered Leek has long thin leaves with a deep central keel. The Flower stalks emerge around early spring, topped with bell-like white flowers with green veins, bearing some resemblance to snowdrops. The entire plant smells of onion/garlic when crushed.

Now some Foraging Etiquette

There are some rules you should abide by if you intend to forage for food, or for foliage.

Only take what you need-Take no more than you plan to consume or use and try to forage over a wide area rather than picking from one patch. Make sure you’re foraging doesn’t disturb the habitats and environments of the local wildlife.

Leave No trace– Leaving no trace of your presence is a sign you have foraged responsibly. Do not trample or disturb roots and only take when there is an abundance of your chosen food or foliage. This allows the plants to replenish and renew.

Don’t Pick from Private land – If you intend to, be sure to get permission first.

Only Pick from Clean areas – Avoid Roadsides, Industrial areas & Top tip* Foraging from the base of a tree for example would not be wise, the likeliness of a dog previously cocking its leg there…is high! If you intend to consume what you have foraged, wash first.
