Coronopus is a genus of flowering plants in the family Polygonaceae, native to Europe, Asia, and North Africa. The genus includes about 15 species, with the most well-known being Coronopus didymus, commonly known as creeping charlie or creeping willow. Coronopus plants are annual or perennial herbs, typically growing to a height of 30-120 cm. They have alternate, simple leaves with entire margins, and small, inconspicuous flowers that are usually white or pinkish, arranged in dense clusters. The flowers are typically 3-5 mm in diameter and have five petals.

Coronopus species are often used as ornamental plants in gardens and landscapes due to their attractive foliage and compact growth habit. They are also used in traditional medicine, particularly in Europe, where they have been used to treat various ailments, including digestive issues and skin conditions. The plant contains several bioactive compounds, including flavonoids and tannins, which are believed to contribute to its medicinal properties.

Coronopus plants are relatively easy to grow and can tolerate a wide range of soil conditions. They prefer full sun to partial shade and require moderate watering. The plants are also known to be invasive in some regions, particularly in North America, where they have been introduced as an ornamental species. However, they are not considered a significant threat to native ecosystems and are generally considered a low-risk invasive species.

In summary, Coronopus is a genus of flowering plants that includes several species used as ornamental plants and in traditional medicine. The plants are relatively easy to grow and can tolerate a wide range of soil conditions, but they can also be invasive in some regions.
