Sedum sanhedrinum (Sanhedrin stonecrop) is a native California perennial in the Crassulaceae family, recognized by detailed morphological features available.
Sanhedrin stonecrop is a rare (CNPS 1B.2) California native perennial found in rocky mountain habitats at elevations of 1,400 to 2,300 meters. Flowering from June to August, this plant produces yellow to whitish flowers with pink or red midribs, arranged in compact head-like clusters 7 to 8.5 centimeters long. Growing with slender glaucous stems 5 to 23 centimeters tall, it forms dense rosettes in sunny locations with tightly clustered internodes. Its leaves are distinctively flattened, with rosette leaves 20 to 30 millimeters long, broadly obovate to oblanceolate, and stem leaves alternating and ascending. The plant's flowers feature delicate yellow to white filaments and anthers that age from yellow to pink, red, or white.
