The genus Santolina, or cotton lavenders, occur in the Mediterranean, where they thrive in dry, rocky habitats, so particularly enjoy well-drained soil in full sun.  This selection has finely divided, grey-green, fragrant foliage, and produces contrasting creamy-white flowers.  These are produced in button-like heads, in which several tiny flowers are held in a tight cluster surrounded by rows of involucral bracts.  It is a member of the daisy family, Asteraceae, which is one of the largest plant families comprising approximately 1600 genera.
