Astrida and I are going to do some indigo dyeing today. I realized that I know nothing about the indigo plant, so did some research (thank you, internet).
True indigo is a legume with pink or violet flowers. 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.
Dye is obtained from the processing of the plant’s leaves. Today most dye is synthetic, but natural dye from I. tinctoria is still available, and that’s what we’re going to be using today.
