Language English Vegetables and herbs French tarragon (Artemisia dracunculus 'Sativa') Photo: Jardin botanique de Montréal (Josée Bouthot) OngletsBotanyOrigin and description French tarragon is native to Central Asia or Siberia. It gets its Latin name from its curled snake- or dragon-shaped roots. It is an important herb in French cuisine and contains an essential oil similar to that in anise. Because the oil evaporates when the herb is dried, fresh tarragon has a more delicate flavour and much better aroma.Cycle: Perennial.Spacing: 30-40 cm.Height: 30-60 cm.
