Sedum albomarginatum is a rare species of flowering plant in the stonecrop family known by the common name Feather River stonecrop. It is endemic to California where it is known from fewer than 20 occurrences along the Feather River in Plumas and Butte Counties.[1][2] It grows on steep cliffs and mountain slopes in rocky serpentine substrates.

Description[edit]

Sedum albomarginatum is a small perennial succulent plant forming basal rosettes a few centimeters wide from a woody root system. The leaves are up to 6 mm long. with the widest part near the distal end, then narrowing to a rounded or slightly notched tip. Smaller leaves occur farther up the stem. The leaves are hairless, waxy, and blue-green in color, often with characteristic white edges where the wax is thickest.[3] The inflorescence is a spreading array of many flowers with light yellow petals up to a centimeter long each.

Threats to this rare Sedum species include erosion on the steep terrain where it grows, as well as mining and construction.
