Isatis tinctoria
The first archaeological finds of woad seeds date to the Neolithic. The seeds have been found in the cave of l'Audoste, Bouches-du-Rhône, France. Impressions of seeds of "Färberwaid" (Isatis tinctoria L.) or German indigo, of the plant family "Brassicaceae", have been found on pottery in the Iron Age settlement of Heuneburg, Germany. Seed and pod fragments have also been found in an Iron Age pit at Dragonby, North Lincolnshire, United Kingdom. The Hallstatt burials of the Hochdorf Chieftain's Grave and Hohmichele contained textiles dyed with woad.
