Rubia tinctorum

Rubia tinctorum, commonly known as common madder or dyer's madder, is a perennial climbing herb in the coffee family.

Native to the Mediterranean region and Western Asia, it was once cultivated across Europe for its roots, which yield the famous red dye known as alizarin.

The color is extracted from its roots, known as rhizomes, which are naturally orange-yellow and turn fluorescent red when exposed to oxygen.

The flowers of Rubia tinctorum are small and star-shaped, usually yellow-green, modest in size but numerous. These flowers are pollinated by small insects, mainly bees and flies, and give way to tiny round black berries by late summer. The fruits are not ornamental but serve an ecological function, attracting birds that disperse the seeds.

The foliage of madder is distinctive: narrow, lance-shaped leaves arranged in whorls of four to six around the stem, forming a regular, almost geometric pattern.

The surface of the leaves is slightly rough, another climbing aid, and they remain an attractive, deep green throughout the growing season.

Below ground lies the most valuable part of Rubia tinctorum — its thick, fibrous roots, which can extend over a meter in length.

These roots store the red dye compound alizarin, and for centuries they were harvested, dried, and ground to produce vibrant shades of red, rose, and orange for textile dyeing.

Before the advent of synthetic dyes in the 19th century, madder was one of Europe's most important dye plants, grown commercially in France, the Netherlands, and the Levant. Even today, natural dyers prize it for its depth of color and historical significance.
