Catchweed refers to a type of plant, specifically a common name for certain members of the genus *Galium*, particularly *Galium aparine*, also known as cleavers or sticky weed. This plant is characterized by its climbing or sprawling habit and its small, sticky leaves and stems that can cling to other plants or surfaces. It is often found in gardens and fields and is known for its ability to stick to clothing and animal fur due to its bristly texture. In some contexts, “catchweed” may also refer to other plants with similar clinging properties.
