About True indigo
Indigofera tinctoria, commonly known as true indigo, is a shrub from the Fabaceae family, renowned as the original source of indigo dye. It features bright green pinnate leaves and small pink or purple flowers clustered in racemes, making it an attractive plant for tropical gardens or large pots in temperate climates.
