Isatis tinctoria, also called woad, is a flowering plant in the family Brassicaceae. It is occasionally known as Asp of Jerusalem.
Since ancient times, woad was an important source of blue dye and was cultivated throughout Europe, especially in Western and Southern Europe. In medieval times there were important woad-growing regions in England, Germany and France. Towns such as Toulouse became prosperous from the woad trade.
Last year we joined a small allotment community and besides planting things you can eat we put some woad seeds in the soil. That season we had tiny plants and I’m not really sure why. We left them and this second season they suddenly started to grow very fast with great bright yellow flowers that turned into deep purple seeds.
Half of the Woad leaves are picked and the seeds are drying in our workspace. Next step is turning some cotton in a sweet woad blue!
We have a lot of seed now, so if you are interested in growing Woad yourself please contact us.
