Rubia
A group of plants whose roots once dyed cloth and paint a lasting red
No single value: Rubia is a material, and its colour varies. The background shows its family, red.
Rubia is a genus of climbing plants best known for their roots, which yield a red dye called madder. This dye, used since ancient times in Asia, Europe, and Africa, coloured textiles, paints, and even Easter eggs. The main colouring agent is alizarin, now mostly made synthetically.
- Rubia roots were the main source of madder red dye for centuries
- Alizarin is the key chemical in Rubia that gives the red colour
- Madder-dyed cloth has been found on Egyptian mummies
- Rubia is still used to dye Easter eggs red in Georgia and Armenia
What colour is Rubia?
Rubia refers to a group of climbing or scrambling plants whose roots produce a red dye. This dye, known as madder, gives a deep, lasting red that was once common in textiles and paint. The colour comes from a chemical in the roots called alizarin. Rubia鈥檚 red stands out for its earthy, slightly bluish tone, different from brighter or more orange reds.
Where does Rubia come from?
The name Rubia comes from the Latin word for red, 'ruber'. The plants are native to the Old World and have been grown for their dye since ancient times. Madder was known in Egypt, Greece, and Rome, and its use spread across Asia and Europe. The dye was important enough to be mentioned by writers like Pliny and Dioscorides. Its role faded after alizarin could be made in factories.
How is Rubia made?
The dye is made from the roots of Rubia plants, especially Rubia tinctorum, Rubia cordifolia, and Rubia peregrina. The roots are dug up, dried, and processed to extract alizarin, the main red colouring. This dye was once used to make Rose madder for textiles and Madder lake for paint. Today, most alizarin is made synthetically.
Where Rubia is used
Rubia dye coloured cloth for centuries in places like Egypt, India, and Europe. It was also used in paint, especially as Madder lake. In Georgia and Armenia, it is still used to dye Easter eggs red. The dye鈥檚 use in textiles declined after synthetic dyes became available, but it remains part of traditional crafts in some regions.

Several species of Rubia were used for dye, with Rubia tinctorum common in Europe and Rubia cordifolia in India. The dye is sometimes called Rose madder or Madder lake, depending on its use. Synthetic alizarin now replaces most natural madder, but the colour is still known by the old names.
