Corn speedwell is a plant that has its origins in various regions across Europe, Western and Central Asia, and North Africa. This species has spread to both North and South America, as well as pockets of Eastern Asia, Southern Africa, New Zealand, and some parts of the Caribbean. It is particularly adaptable, flourishing in a range of environments far beyond its native range.

Corn speedwell originates from Europe and has earned its moniker as a weed due to its invasive capabilities. With the ability to rapidly multiply and spread, it has become an irritant for gardeners worldwide. Corn speedwell's resiliency allows it to flourish in various environments, making it a potent threat to gardens. A single plant can produce numerous seeds which ensure its proliferation in a short amount of time. Its rapid and expansive growth can be harmful, outcompeting native plants and causing significant damage to garden biodiversity. The primary form of its spread is through its seeds, which are typically dispersed by the wind or by adhering to animals, footwear, or garden tools. By so doing, corn speedwell secures its presence in a new habitat, and continues its invasive spread. While not directly harmful to humans, its invasive nature can compromise the quality of the soils and habitats it invades, making it particularly troublesome to gardeners and horticulturists.

The best season to remove corn speedwell is late spring or early summer when the plant is actively growing but before it has a chance to start flowering and setting seed. Here are a few organic or creative methods to eradicate corn speedwell:
