One of the most stunning trees in India - Butea monosperma flowers during spring time and its red flowers have been used to make natural colour. Palash is now a rare tree in urban areas although it is still found in the interiors of Maharashtra.
Making dye from Flame of the Forest is rather simple. After collection, the flowers are chopped into small pieces, boiled with water, and strained. Once heated, the resulting liquid can be used to dye fabrics anywhere from soft yellow to bright orange, depending on the soaking time, pH, and temperature. ( Source: Avani)
