About Asperula tinctoria L.
Asperula tinctoria, commonly known as dyer's woodruff, is a flowering plant species belonging to the Rubiaceae family. It is native to most of northern and central Europe, ranging from France eastward to Russia, and is also found native in Western Siberia. The root of this plant was used by ancient Greeks and Romans to produce a red dye for clothing. However, it was less productive than Rubia tinctorum (madder), which was far more widely used for this purpose.
