Sedum is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as Sedum are now in the segregate genera Hylotelephium and Rhodiola.

S. sexangulare is about 15 cm (5 in) tall and is native to Europe and Asia, where it grows in the wild and is often cultivated as an ornamental plant. The plant needs wet or dry sandy soil and a sunny spot. It blooms in June and July with yellow, star-shaped flowers, which attract bees and other insects.

Sedum spathulifolium is a species of flowering plant in the family Crassulaceae known by the common names broadleaf stonecrop, yellow stonecrop, and spoon-leaved stonecrop. An evergreen perennial, it is native to western North America from British Columbia to southern California, where it can be found often in shade in many types of rocky habitat in coastal and inland hills and mountains.
Sedum stenopetalum is a species of flowering plant in the family Crassulaceae known by the common name wormleaf stonecrop, or golden constellation. It is native to western North America from British Columbia and Alberta to northern California to Wyoming. It can be found in many types of rocky habitat, such as cliffs, talus, and steep ridges. It is a succulent plant producing mats or clumps of lance-shaped, linear, or three-lobed leaves each under 2 centimeters long. The inflorescence is a short, erect array of one to many flowers with lance-shaped petals up to a centimeter long. The petals are yellow, sometimes with red veins.
Sedum villosum, known as the hairy stonecrop or purple stonecrop, is a biennial to perennial flowering plant. Its leaves, which are 3–8 mm (0.1–0.3 in) long and may be reddish in colour, are generally covered with hairs, although S. villosum var. glabratum may have hairless leaves. Individual flowers have five pink petals, each up to 5 mm (0.2 in) long.
