Veronica arvensis, commonly known as corn speedwell, is a species of flowering plant from the genus Veronica. It is an annual herbaceous weed that belongs to the Plantaginaceae family. This invasive species is found in pastures, meadows, croplands, and disturbed areas throughout Europe and North America. Given its widespread distribution, this plant has acquired different names depending on the region. Some synonyms of Veronica arvensis include common speedwell, field speedwell, bird's eye, gypsy-weed, and creeping veronica. Despite its harmless appearance, corn speedwell competes with crops for nutrients and water, leading to reduced yield and profitability for farmers.
