Anise, aniseed – same thing: an annual herb (parsley family, FYI), which grows in the eastern Mediterranean region and south-west Asia, and has a strong licorice/fennel/tarragon flavour, often enjoyed in alcoholic drinks or sweeties (the famous aniseed balls of your granny’s childhood…)
It’s sweet and very aromatic, and really very popular in perfumery as a result: the most celebrated example is Guerlain’s gorgeous, iconic L’Heure Bleu. (Not to be confused with Star anise – although the key component of the essential oil, ‘anethole’, is actually found in both.)
