Did the Romans take their Leeks to Wales?

The Romans gave us roads, plumbing, wine and irrigation and now it seems they may have also introduced Wales' unofficial icon - the garden leek.

The National Museum of Wales says the Romans probably planted domesticated varieties to flavour their stews.

The museum has recreated a Roman-design garden at the National Roman Legion Museum in Caerleon, near Newport.

The garden aims to show how troops posted to the edge of the empire created their own home-from-home.
