While in Oaxaca, Mexico, a friend gave me a small bag of dried dye material. She had obtained it from dyers in the Teotitlan Valley. It was identified locally as “Mexican chamomile”. It was very aromatic and easy to believe that it was a type of chamomile, possibly related to dyer’s chamomile (Anthemis tinctoria), also known as know as golden marguerite.
I wanted to compare this “Mexican chamomile” with the chamomile I had at home. I had dried chamomile flowers from Maiwa and some whole plants from the end of the season in my garden. Both of them were Anthemis tinctoria.
I dyed mordanted wool fabric with all three of these “chamomiles” and achieved very different results. Both of the known chamomile dyes produced in a soft, predictable yellow color while the Mexican “chamomile” produced in a much deeper, richer tone. When I completed lightfast tests on the three samples, the Mexican chamomile actually deepened in hue, which led me to believe that it contained a tannin. I guessed that it might not actually be chamomile.
After reporting these results to the friend who had given me the dye, she told me the plant had another local name: “pericon”. Once I knew this, it was easy to identify the plant in both Tintes y tintoreros de América by Ana Roquero and Plantes Tintóreas de Guatemala by Olga Reiche. Both of these are excellent dye books, written in Spanish.
The dye plant in question was Tagetes lucida, a type of marigold. The entire plant is used for dyeing, which explains the presence of tannin in the dye. The whole plant is likely to contain tannins while the flowers alone would not.
I have located sources of seed for this plant. The seed companies also refer to it as “Mexican tarragon”, “sweet smelling marigold”, and “Mexican mint marigold”. The leaves are a savory herb and can be used as a substitute for tarragon.
I bring all this up to emphasize the importance of using Latin names for our dye plants. Local names are only useful to local people. I understand that there is a great deal of emphasis on the use of local plants for dyeing but as we travel and meet dyers from other places it becomes important to talk about our process in a common, international language.
While in Mexico I took a workshop on plant taxonomy with Alejandro de Ávila at the Botanical Gardens in Oaxaca. I marvel at the incredible system of plant names that can be understood around the world and encourage dyers to get into the habit of using the Latin names for plants.
I will grow Tagetes lucida (or “Mexican chamomile”, or “pericon” or Mexican tarragon” or “sweet smelling marigold” or “Mexican mint marigold”) in my garden this year and think about the Teotitlan dyers who gather it wild and use in their weavings.
