Cudweed is a plant naturally occurring in a wide expanse across the temperate Northern Hemisphere. It is native to regions that include North Asia, parts of Eastern Asia, the northern reaches of Europe, and extends into North America's temperate zones. This plant has established itself across these major regions without necessarily being introduced by human activity.

Cudweed, also known as Galium triflorum or Cudweed, originates from North America. It is viewed as a weed due to its rapid growth and broad distribution. Its capability to survive in various soil conditions, including difficult ones, makes it hard to eradicate once settled. This plant's invasiveness stems from its prolific reproduction, both through its multitude of seeds and vegetatively via its creeping rhizomes. These characteristics enable cudweed to out-compete native plants for resources such as space, light, and nutrients, potentially causing significant harm to gardens. The dominant medium of its spread is through seeds that get dispersed by wind, water, or through animals. Its underground stems, rhizomes, also contribute to its spread, thereby making it a stern challenge for gardeners.

The best season to remove cudweed is in the late spring or early summer before the plant has had a chance to flower and spread its seeds. Ideally, you will want to control this plant when it's still young and hasn't seeded.
