Galium aparine

Common Names: Cleavers, Goosegrass, Sticky Willy, Catchweed, Grip Grass, Bedstraw

🧭 Description & Habitat

Cleavers is a fast-growing annual plant with straggly stems covered in tiny hooked hairs, enabling it to cling to clothing, animals, and other plants. It has slender, whorled leaves and small, star-shaped white flowers. Native to Europe, North Africa, and parts of Asia, it thrives in hedgerows, woodland edges, gardens, and waste ground—particularly moist, shady areas.

📜 History & Ethnobotany

Cleavers has a long tradition of use in European folk medicine as a spring tonic and lymphatic cleanser. Historically, it was used to relieve swollen glands, urinary tract infections, and skin conditions. In medieval times, it was used to stuff mattresses due to its clingy nature, and its seeds have been roasted and used as a coffee substitute. Native American tribes also used it as a gentle diuretic and topical poultice.

When fresh, the tender stems can be eaten in salads or blended into green juices (in small quantities).
