Blueberry (indigofera tinctoria)

Blueberry, scientifically known as Indigofera tinctoria, is a plant prized for producing a rich, deep blue dye historically used in textiles. Native to Asia, it has feathery green leaves and small pink flowers, maturing into pods that contain the dye origin. The dye is extracted from the leaves through a fermentation process, resulting in indigo, a color valued for its vibrant and lasting hue. Beyond dyeing, the plant has been used in traditional medicine. Its importance lies in its historic role in producing the iconic blue of denim and many traditional fabrics worldwide.
