Also known as yellow bedstraw, or bed flower, it's thought to get its name because its dried flowers were traditionally used for stuffing mattresses. When dried, the flowers smell of hay, and the scent was said to repel fleas. It also has associations with helping women giving birth – it's thought to have a sedative effect.

Galium verum is also known as rennet weed, or cheese rennet, as the plant contains an enzyme that curdles milk, making it a useful alternative to rennet in cheese production. The plant was also used as a dye and was even used to give Double Gloucester cheese its distinctive colour.
