EVERGREEN SEDUM: Stonecrop
Sedums, or stonecrops, are easy to grow given good drainage and adequate sun. They are economical because they grow quickly, and are simple to propagate. Plus they are outstanding performers in containers, pathways, parking strips and much more. Their durability with drought conditions and shallow soil has helped them become the stars of green roof and living wall designs. Their range of foliage color and texture make them perfect plants for living art such as hanging pictures, wreaths and much more.
If you want your creations to have year round interest it is nice choose varieties from the following list of creeping types, all of evergreen or semi-evergreen in Portland (USDA zone 8).

Zone 4. ‘Angelina’ (shown here) has golden yellow leaves that take on orange and red tints during the fall.
S. sexangulare (Six sided stonecrop) - Chubby, elongated green leaves spiral up 3-4” stems. Sprays of bright yellow flowers in summer. Zones 2-9.

S. spurium - Semi evergreen (rosettes persist at the end of the stems through winter). Grows about 4 inches tall, spreads well and is good for covering banks and slopes.

Origin: Sedums come from the Northern hemisphere, with around 400 species coming mostly from mountainous areas.
Culture: Full sun in well-draining, poor to moderate soil. Drought-tolerant but appreciates some water at flowering time.
Maintenance: Shrubby-type sedums need to be cut down to the crown in the late fall once foliage starts to look bad, or in the spring if the seed heads are left for winter interest. The shrubby-types also might need staking if they are in too rich of soil. Creeping sedums benefit from having the flower heads cut back to maintain their shape. Easy!
Because of their diverse looks and sizes, they fit many roles in the garden or as container plants. Many groundcover varieties are evergreen or semi-evergreen while the taller sedums die back to the ground to re-emerge as cute rosettes in spring.
Propagation: Easy to propagate from stem cuttings, sometimes detached leaves will even root and form new plants.
Pests and Diseases: Snails and slugs can be a problem early in the season.
