Natural Indigo Dye is obtained from the processing of Indigo leaves. They are soaked in water and fermented in order to convert the glycoside indican naturally present in the plant to the blue dye indigotin. 

The precipitate from the fermented leaf solution is mixed with a strong base such as lye, pressed into cakes, dried and powdered. The powder is then mixed with various other substances to produce different shades of blue and purple.

Blue Wild Indigo

The Blue Wild Indigo (Baptisia australis) also known as Blue False Indigo, is a North American herbaceous perennial plant that was used by the Cherokee Indians to make a blue dye. 
Our indigo leaves are also used for making hair dye.

Indigo Leaves

Most natural indigo dye is obtained from indigo leaves in the genus Indigofera, which are native to the tropics. 
In Europe, Indigo can be obtained from wood (Isatis tinctoria) and dyer's knotweed (Polygonum tinctorum). 
The primary commercial indigo species in Asia is true indigo(Indigofera tinctoria), a shrub found in Southeastern Asia. Its flowers range from red to purple.

Indigofera Tinctoria

Indigofera tinctoria bears the common name true indigo. The plant was one of the original sources of indigo hair dye. It has been naturalized to tropical and temperate Asia, as well as parts of Africa, but its native habitat is unknown since it has been in cultivation worldwide for many centuries.
