Spergula is a genus of annual flowering plants in the family Caryophyllaceae (the pink or carnation family), placed within the order Caryophyllales. The genus is commonly known as spurry or spurrey and comprises around ten accepted species distributed across Eurasia, Africa, and portions of South America.
Plants in this genus are slender-stemmed annuals with whorled, thread-like leaves — a characteristic form shared with relatives in the broader Caryophyllaceae family. They typically produce small white flowers and are well adapted to open, disturbed ground. Members of the genus are most commonly encountered in grassland, arable fields, and sandy or nutrient-poor soils.
The best-known member is Spergula arvensis (corn spurrey), a widespread weed of cereal crops and disturbed ground across temperate regions of the northern hemisphere, historically also gathered as a fodder plant in parts of Europe.
Etymology
The name Spergula derives from Latin spargere, meaning "to scatter" or "to spread," likely a reference to the plant's freely spreading or dispersed seeds. The common English names spurry and spurrey are vernacular corruptions of the genus name.
Distribution
Spergula species are native to portions of Eurasia, Africa, and South America, and are commonly found in grassland and open habitats. Spergula arvensis, the most widespread member, has spread as a weed of arable land throughout temperate regions worldwide.
Ecology
Species of Spergula are typically associated with open, disturbed habitats including grassland, sandy soils, and cultivated fields. Spergula arvensis is a well-known arable weed, thriving in nutrient-poor, acidic soils where it competes with cereal crops.
