Reseda Luteola - Färber Wau

Reseda Luteola, also known as Gelber Wau or Färber Wau, is a species that has played an important role in botany and human history for centuries. This plant, which belongs to the family of the red -faces (Resedaceae), is not only characterized by its fascinating botany, but also by its historical importance in dyeing and medicine.

Botanical characteristics

Reseda Luteola is a herbaceous plant that can reach a height of around 30 to 100 centimeters. The plant is characterized by its yellow, hermaphrodite flowers, which are arranged in a dense panel. Each flower consists of five yellow crown leaves and five stamens. The leaves of Reseda Luteola are elongated and alternately arranged. The roots are fibrous and go down, which makes the plant resistant to dryness. The fruits are pattern -like capsules that contain numerous seeds.

Ecological distribution

Reseda Luteola is native to Europe, North Africa and parts of Asia. The plant prefers dry, limed floors and can be found in light forests, meadows and on the edges of the path. It is a pioneer plant that can adapt well to different locations. Reseda Luteola has also become natural in North America and is considered an invasive way in some regions.

Historical use

One of the most remarkable properties of Reseda Luteola is its historical use as a dye. The plant contains luteolin, a yellow dye that was already used in antiquity and in the Middle Ages to color textiles. Gelber Wau was so popular in the dyeing that it is even mentioned in the Bible. In ancient Egypt and in the Roman Empire, Reseda Luteola was used to produce yellow dyes. In the Middle Ages, the plant was widespread in Europe and was valued by dyers. Its use in the dyeing flourished in the 15th century when it was used to produce the famous "Naplesgelb".

Current importance

Although the importance of Reseda Luteola in the dyeing has decreased over time, the plant is still grown in some parts of Europe for the production of natural dyes. In modern botany and pharmacy, the plant is researched due to its wealth of luteolin and other bioactive connections. These connections have potential medical applications and could play a role in developing new medication and therapies.
