Indigofera tinctoria / നീല അമരി

Indigofera tinctoria (True Indigo / നീല അമരി) is a historic dye and medicinal plant, the classic source of natural blue indigo dye. Beyond dyeing, it is valued in Ayurveda for hair care and traditional remedies, and enriches soil by fixing nitrogen. Sow the seeds in warm, well-draining soil in full sun; the hardy shrub grows easily in tropical climates with little care. A wonderful choice for natural dyers, herbalists and eco-gardeners, indigo thrives in garden beds and large pots — a beautiful, useful and sustainable plant to grow.
