Conservation status: CNPS 4.3

Heckner's stonecrop is a native perennial found in the Klamath Ranges and northern North Coast Ranges on cliffs, dry rocky slopes, and road cuts at elevations of 100 to 2,200 meters. Flowering from May to August, this plant produces flowers with red to dark red anthers that age to black, set against a pale glaucous stem. Growing 9 to 29 centimeters tall with distinctive rosette leaves, its leaf structure is particularly noteworthy with obovate to broadly obovate leaves 12 to 37 millimeters long that often have notched or blunt tips. Its stem leaves are broadly shaped, typically suborbicular to broadly obovate, spreading or slightly ascending and slightly clasping at the base. The plant's petals measure 7 to 13 millimeters long, creating delicate clusters on varied rocky substrates including argillite, chert, shale, and serpentine.
