Sedum hispanicum

Fine-textured and reliably beautiful, Sedum hispanicum is one of the mat-forming sedums that earns its keep through sheer consistency of good looks. The foliage is composed of tiny, cylindrical, glaucous blue-gray leaves packed densely along spreading stems — finer in texture than most sedums, with a soft, almost powdery appearance that's particularly attractive in the oblique light of a Pacific Northwest morning. White to pale pink flowers appear in late spring to early summer, small and numerous, covering the mat in a delicate and pleasing flush.

Hardy to Zone 4 and performing reliably in PNW rock gardens, S. hispanicum handles dry summers and wet winters with the equanimity of a plant native to the rocky Mediterranean slopes of Spain and southern Europe — conditions with obvious parallels to PNW summer-dry gardens. Full sun and excellent drainage are the main requirements. It's a natural companion for coarser-textured rock garden companions, where its fine foliage creates contrast. Stepping stone paths, gravel beds, dry stone walls, and detailed alpine troughs all suit it well. There's a timeless, classic quality to Sedum hispanicum that has kept it in cultivation for generations — not flashy, just quietly excellent, season after season.
