Title: Searching for a dye made from a French weed
Answered by: Nan Hampton

QUESTION:

Dear Mr smarty plants, I watched a gardening show on cable and they talked about a place in France where they use a weed called Wod to make dye and dye fabric and several other items to sell. It was fascinating and I wanted to learn more about this weed and the dying process. Or even where in France they make this dye, and if you can purchase their products. Have you ever heard of this plant? They said Marys' dress was dyed with this color, it is very long lasting and does not fade. I hope you can give me some information on this. Thank you so much,

ANSWER:

Mr. Smarty Plants thinks he has found your plant.  You can read a fascinating history (by Professor Arthur C. Gibson, who teaches a course on economic botany at UCLA) of Isatis tinctoria (Woad), a European member of the Family Brassicaceae (Mustard Family), the plant used for blue dyes for centuries in Europe. Not only was it used for dyeing fabrics but also was used in the British Isles as a body dye to frighten foes.  (Remember Mel Gibson's facepaint in the movie "Braveheart"?)  There is another website called The Woad Page that gives more history of the dye and its uses. There are also links to suppliers of woad powder in France and in England on this page as well as instructions for making the dye from the plants and dyeing with it.  Now that you know the correct spelling of its name you can probably find U.S. sources for woad powder by googling on the name.  Or, you could collect and make your own dye since Isatis tinctoria (Dyer's woad), though not native, grows and is considered invasive over most of the western United States, including Utah where it is appears on the Utah State-listed Noxious Weeds. Here is link to photos from University of California-Berkeley's CalPhotos site.
