There were originally two sedum plants in the garden, now they are all around, filling what would have been empty spaces. They are easy to divide and replant because their roots are relatively shallow and their succulence helps them survive till the roots establish in their new locations. Unlike some other hardy perennials, they only grow where and when you want them to; they don't produce unwanted suckers and they don't return once removed.
In winter after the leaves had shed, the dried stems and coppery flowers stayed intact despite wind, rain and snow.
I broke off the stalks when the shoots appeared, they looked like little jade rose buds, developing quickly in early summer into compact, pin-cushion-shaped, self-supporting clumps.
The sedum on the left lives under a bush; its leaves are bigger and darker than the other plants and it's growing horizontally searching for sunlight. The little plant on the right was a stray stem, without any roots, remaining after dividing the sedums last autumn. I just stuck it in the soil of the driest flower-bed and it stayed alive. It's ageing quicker because it's exposed to more sunshine.
