Cleavers
Galium aparineCleavers are so called because the plant is covered with little hooks, like velcro, that allow it to "cleave to" other plants, animals, and pant legs. (
"To cleave" has two different, opposite meanings.) Likewise it may be called "sticky willy," "catchgrass," "catchweed bedstraw" (because a related was used to stuff bedding), and for some reason "goosegrass."

The plant is native to both Eurasia and North America, and has a history of cultural use in both continents. A variety of medical and culinary uses (including roasting the seeds as a coffee substitute) are attached to it, though contemporary people know it mainly as a weed. It prefers richly fertilized soil, and becomes a pest of crop fields and yard edges. Outside of its native range it is considered invasive.
