Sedum lanceolatum
Sedum oreganum
Rock outcrops, cliffs, steep rocky slopes. Flowering Jun–Aug. 0–1500 m. Casc, CR, Est, WV. CA, WA; north to AK. Native.
Sedum oreganum is recognized by its plump, shiny, crowded leaves and its long, narrow, erect, yellow flowers. Sedum divergens has more nearly spherical, opposite leaves. Sedum oreganum is sometimes divided into coastal (S. o. ssp. oreganum) and Cascadian (S. o. ssp. tenue) subspecies. Because Sedum disperse poorly, a biologically significant difference may have developed between these disjunct populations. However, the reported morphological differences do not appear to differentiate the populations consistently.
