Sedum oregonense (Cream stonecrop) is a native California herb in the Crassulaceae family, recognized by loose rosettes and cream flowers on non-serpentine.
Cream stonecrop is a California native perennial found in the Klamath Ranges in outcrops, sunny rocky slopes, and forest openings at elevations of 1,000 to 2,500 meters. Flowering from June to September, this plant produces white to cream flowers in compact clusters 2.6 to 9 centimeters long, with petals 7 to 13 millimeters long. Growing with glaucous stems 7 to 26 centimeters tall and forming loose rosettes, it spreads through numerous stout stolons in sunny locations. Its rosette leaves are distinctive, broadly obovate to oblanceolate, 14 to 33 millimeters long with rounded or notched tips, while stem leaves become progressively smaller toward the top of the plant. The mature plant produces erect follicles 6 to 9 millimeters long, with small pear-shaped seeds that are finely striate.
