Global Indigo Internship

The mysteries of plant blue: from plants to color

In the heart of nature, in the heart of the Lilas micro-farm, with Cécilia Aguirre you will reap  persicaire feet and learn a pigment extraction technique by making this famous blue gold yourself.

The course offered here focuses on aspects of indigo, the famous blue pigment from plants. Two traditional plants will be discussed: pastel, and more particularly  persicaria indigo (the traditional Japanese plant). 

The trainees will learn the culture of these plants, the different methods of pigment extraction, manufacture of cocagnes, the assembly of a tank and the basics of indigo dyeing.

Restorer of works of textile art and farmer, passionate about vegetable dyes and plants, I founded the Lilas micro-farm with the desire to share these passions and raise public awareness of our connection to the earth.

The transformation of indigo is for me an exciting path, a captivating alchemy that I enjoy discovering every year on the farm, starting from the source: the earth and the plant.
