Petrosedum sediforme 'Silver', is a glaucous cultivar of Petrosedum sediforme, the Pale Stonecrop. Its greyish-blue colouration is a great contrast with the pinkish-red tones it develops on its lower stems as it matures. Like the type species, it is is an tough drought-resistant groundcover that is very easy to grow, providing a low-maintenance carpet for gravel gardens, rockeries or to sprawl down the face of a stone wall, its roots tucked into nooks and crannies.
