Lemon tree is a small evergreen tree native to Asia. Lemon tree is grown for its yellow fruit that is rich in a zest refreshing juice, which is a key ingredient in many drinks and foods. Lemon tree entered Europe in 1st century AD, in Ancient Roman times, and it was introduced to the Americas by Christopher Columbus, back in 1493. In the early days, lemon was mainly used as ornamental plant and for medicine, but today it is used in aromatherapy, for cleansing, as a deodorizer and even to produce electricity for low power “lemon batteries.” One of the great international music hits of the 90’s, a song by German britpop band Fool’s Garden, was named after this plant – “Lemon Tree.”
