A tasteless little stonecrop
Sedum sexangulare, known as tasteless stonecrop, is a low, vigorous evergreen succulent in the Crassulaceae family. It forms a dense, creeping mat of tiny cylindrical leaves and, in summer, sends up starry yellow flowers above the foliage.

A European native
This sedum's natural range lies across Europe, and it is not native to Britain or Ireland. It has long been grown in rock gardens and alpine collections for its toughness and ground-covering habit.

Sun, shelter, sharp drainage
Give it full sun in a sheltered spot, ideally a south- or west-facing aspect, and moderately fertile, well-drained soil that is alkaline to neutral. It tolerates chalk, loam or sand and takes drought well, asking little beyond good drainage and light.

Rooting from softwood cuttings
New plants are raised from softwood cuttings, taken in the usual way for succulent stonecrops.
Source: RHS
Dense mats, starry blooms
The plant grows to about 10cm tall, with succulent, cylindrical leaves packed tightly along rooting, creeping stems in an evergreen mat. Come summer, masses of small, star-shaped yellow flowers rise on stems above the foliage.

Watch for vine weevil

Rot in wet conditions
Fungal and bacterial crown and root rots can set in, generally where drainage or shelter is lacking.

A trim after flowering
Once the flowers fade, trim the mat back to keep its shape tidy.
