Unlike English Stonecrop, White Stonecrop stands a little taller. Relatively long flowering stalks from 7-15cm which are well-branched.

And has a slightly domed head of many (more than 20) flowers on a branched stalk. Leaves alternate like many other Stonecrops. And very white petals, with little or no pinkish tinge.

The pinkish stalks have fewer stubby and fleshy leaves and which are 6-12mm long (twice as long as the 3-6mm on English Stonecrop).

The petals come to a sudden nearly obtuse-angled termination (un-like those on English Stonecrop which taper slowly to an acute-angled point). Here they are also slightly reddened.

Exposure to strong sunlight in an short gryke atop the Great Orme will turn the leaves red.

Two white stars stacked upon each other, the lower set of 'arms' are the petals, the upper contain the fruits.


Some similarities to : English Stonecrop (Sedum anglicum) but the flowers of White Stonecrop are more often pure white and only occasionally tinged pink, whereas they are always white tinged pink on English Stonecrop. The leaves of English Stonecrop are 3-6mm long (half as long as the 6-12mm of White Stonecrop). English Stonecrop has grey-green leaves whereas the leaves of White Stonecrop) are bright green. Both are often tinged red, but English Stonecrop are often heavily washed or streaked with red, especially on ovaries and stigmas. The petals of English Stonecrop are more pointed than those of White Stonecrop which have a more abrupt obtuse. The anthers are dark-red on both English Stonecrop and White Stonecrop, but White Stonecrop (up to 570m altitude) cannot grow as high as does English Stonecrop (1080m).

An archaophyte that is an evergreen succulent and which can grow on a variety of differing substrates ranging from dry banks, rocks and shingle to man-made structures such as roofs, walls, paths, gravestones and crumbling concrete.
