Sedum kiersteadiae (Mount eddy stonecrop) is a native California perennial in the Crassulaceae family, recognized by distinctive loose rosettes with visible internodes.
Mount eddy stonecrop is a California native perennial found in the high Cascade Range and Sierra Nevada Mountains on serpentine outcrops, ridgelines, and rocky forest slopes at elevations of 1,100 to 2,400 meters. Flowering from June to August, this plant produces light yellow flowers with pink or red midribs, often aging to red, in compact cylindrical clusters with up to 55 blossoms. Growing with slender stems 7 to 29 centimeters tall, it forms loose rosettes in sunny locations with distinctly spaced internodes.
