A tiny stonecrop
Sedum dasyphyllum, known as thick-leaved stonecrop, is a low, creeping evergreen succulent in the Crassulaceae family. It forms a mat barely reaching 10cm tall, dotted with tiny fleshy leaves, and in summer sends up slender stems topped with creamy-white flowers.

A Mediterranean wanderer
This species is native across central and southern Europe into southwest Türkiye and northwest Africa, with a native range spanning countries from Spain and France to Greece, Albania, Morocco, and Tunisia. It has since been introduced further north, taking hold in Belgium, Denmark, Great Britain, and Ireland. First described by Linnaeus in 1753, it now also counts several accepted subspecies, including granatense and oblongifolium.

Sun, drainage, shelter
Give this stonecrop full sun and a sheltered spot, in moderately fertile, well-drained soil that leans alkaline to neutral, whether chalk, loam, or sand. It is drought resistant and rated hardy through most of the UK, tolerating cold well once established. No particular feeding routine is called for beyond the ordinary care of hardy succulents.

Softwood cuttings
Propagation is done by softwood cuttings, taken from the trailing stems.

Grey leaves, pink stress
The plant's small, silvery-grey leaves crowd tightly along its trailing stems, giving it a soft, matforming habit. Under drought or cold stress those leaves take on a pink or purple tinge, a useful visual cue to its condition. Its creamy-white summer flowers rise on slender stems above this low foliage.

Slugs and sap-suckers
Watch for slugs, snails, and vine weevil grubs, which can trouble the foliage and roots, along with scale insects and mealybugs on the stems and leaves.

Rot in wet conditions
The main problem to guard against is fungal and bacterial crown and root rot, which tends to follow poorly drained or overly wet soil. Sticking to the well-drained, sheltered conditions this plant prefers helps avoid it.

Little upkeep needed
This is a genuinely low-maintenance plant that requires no pruning. It suits rock gardens, gravel gardens, containers, and even garden edging, where its mat-forming habit can spread undisturbed.
