A prickly or spiky weed that produces seeds or fruits with burrs that stick to clothing and animal fur.
From Middle English 'burre' (a prickly seedcase) combined with 'weed' (an unwanted plant). The term evolved to describe any weedy plant whose seeds disperse by clinging to passing objects.
Burweeds are nature's hitchhikers—their sticky burrs inspired George de Mestral to invent Velcro in 1941 after noticing burrs stuck to his dog's fur. This simple observation revolutionized fastening technology across countless industries.
