Galium spurium, the stickwilly[1] or false cleavers, is a plant species of the Rubiaceae. It is widespread across Europe, Asia, Africa and Canada, and is naturalized in Australia.[2][3][4] It is considered a noxious weed in many places.[5]

Galium spurium is an erect or reclining herb up to 50 cm tall. Stems are square in cross-section. Leaves are in whorls of 6–8, narrowly lanceolate. Flowers are in multi-flowered cymes or panicles, white or yellow-green.[6]
