Cleavers (Galium aparine) is a culinary and medicinal herb found around the world in Europe, North America, Asia, Greenland, and Australia. Cleavers is often considered an indicator of high soil fertility, particularly with above-average levels of nitrogen and phosphorus.
This species is a straggling climber, growing up to 3 m long, with slender 4-angled stems. Its narrow leaves can reach 7 cm long and are arranged in groups (whorls) of 6-8 (rarely 4) around the stem. The whole plant is covered in minute hooked hairs, and can cling to skin, fur and clothing. The flowers are tiny, white, 4-petalled tubes, developing into small round fruits, often borne in clusters of two or three. These fruits are also covered in hooked hairs which catch in the fur of passing animals or the clothes of humans.
