Liquorice is part of the Glycyrrhiza genus. Its scientific name is Glycyrrhiza glabra.
The liquorice plant is a legume (related to beans and peas), native to southern Europe and parts of Asia. It is not related to Anise, Star Anise or Fennel, which are the source of superficially similar flavouring compounds. It is an herbaceous perennial, growing to 1 m in height. 1
The flavour of liquorice comes mainly from a sweet-tasting compound called anethole, an aromatic, unsaturated ether compound also found in anise, fennel, and other herbs. Additional sweetness in liquorice comes from glycyrrhizic acid, an anti-viral compound sweeter than sugar. 1It is a herb and is treated mainly as a perennial, so it grows best over a period of time (3 years and greater). Normally grows with a forb habit.
