Ceanothus americanus is a shrub that lives up to fifteen years and growing between 18 and 42 in (0.5 and 1 m) high, having many thin branches.Its root system is thick with fibrous root hairs close to the surface, but with stout, burlish, woody roots that reach deep into the earth—root systems may grow very large in the wild, to compensate after repeated exposures to wildfires.
Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. Some of the colors of autumn leaves are derived from anthocyanins. [1] [2] Anthocyanins belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway.

The pulverised roots can be dissolved in sulfuric acid, which leaves a dye called garance (the French name for madder) after drying. Another method of increasing the yield consisted of dissolving the roots in sulfuric acid after they had been used for dyeing. This produces a dye called garanceux. By treating the pulverized roots with alcohol ...
The roots are baked, roasted, ground, and used as an additive, especially in the Mediterranean region (where the plant is native). As a coffee additive, it is also mixed in Indian filter coffee and in parts of Southeast Asia, South Africa, and the southern United States, particularly in New Orleans .
If you were caught using an “inferior” red dye made from roots like madder, instead of crushed bugs like kermes, you risked losing your savings — or one of your hands. The Alizarin dye ...
