Spergula

Spergula is a genus of plants in the family Caryophyllaceae, commonly known as spurreys. These are typically annual or perennial herbs found in a wide range of habitats across the globe, though they are particularly prevalent in Europe and Asia. Spergula species are often found in disturbed areas, sandy soils, and coastal regions. The genus is characterized by its whorled or opposite leaves, which are usually linear and often fleshy. The flowers are small, typically white or pink, and borne in cymes. The fruit is a capsule containing several small seeds.

One of the most well-known species is Spergula arvensis, the common spurrey. This plant has historically been considered a weed, particularly in cereal crops, where it can compete for resources. However, it has also been cultivated as a fodder crop and for its seeds, which are edible, though not widely consumed. In some regions, Spergula arvensis has been used in traditional medicine. Other species within the genus, such as Spergula sativa and Spergula pentandra, share similar characteristics and ecological niches. The taxonomy of the genus has seen some revisions, with certain species sometimes being placed in related genera.
