Cultivation and Propagation

Galium petrae can be propagated by seed or division. Seeds should be sown in spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division in spring or autumn is also possible. Larger divisions can be planted out direct into their permanent positions, though it is best to pot up the smaller divisions and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
