Indigofera tinctoria, also known as True Indigo, is a historic plant that has been used for centuries as a source of natural dye. Although its native habitat is unknown, it has been naturalized to tropical and temperate regions of Asia and Africa. While synthetic dyes have become more popular in recent years, there is still a market for dye derived from I. tinctoria, which is marketed as a natural coloring. Not only is this plant useful for dyeing purposes, but it is also a great soil-improving groundcover.
