C. limon originates from Asia, and today it is one of the most widely grown fruit trees in orchards and in the home garden. A robust evergreen tree, the lemon can attain a mature height of around 5 metres. Its leaves are large, leathery and aromatic, and borne on slightly drooping branches with very few thorns. New growth tips are tinged with a distinctive purple colour. White, sweetly scented flowers with a purple blush are produced in abundance at regular intervals throughout the year, ensuring that lemons are available almost all year round.
