Sedum radiatum is a species of flowering plant in the stonecrop family known by the common name Coast Range stonecrop. It is native to Oregon and California, where it is known from several coastal and inland mountain ranges, including the Klamath Mountains and the Sierra Nevada. It grows in many types of rocky habitat, sometimes on serpentine soils. It is an annual or biennial succulent plant producing several stems with elevated, somewhat basal rosettes of leaves. The leaves are not much more than a centimeter long. They are green or yellowish with green, purple or red veining. The inflorescence is a short, erect array of many densely packed flowers.

Yellow Stonecrop (Sedum spathulifolium) is a native perennial herb in the Crassulaceae (Stonecrop) family that is found in rocky or mountainous areas over a large part of the state, but more commonly in northern California. It is also found northward to British Columbia. It tends to grow in a hanging or sprawling manner on the face of cliffs or steep rocky outcrops, often in shade, at elevations from 0-7500 feet. The leaves are somewhat thick and succulent. In spring the plant puts up an erect flower stalk with diminutive yellow flowers. This succulent works well in rock gardens in northern California. Plant at an angle so that water does not collect on the crown. In its native setting this plant receives abundant moisture in winter/spring, then remains relatively dry through summer. It is evergreen but may shrivel somewhat in summer.

Grows best in sandy, coarse-grained or other fast draining soil. Selected by Jenny Flemming from the salmon Mountains in northwestern California.
