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.
Crassula is a genus of succulent plants containing about 200 accepted species, including the popular jade plant. They are members of the stonecrop family (Crassulaceae) and are native to many parts of the globe, but cultivated varieties originate almost exclusively from species from the Eastern Cape of South Africa.
Sedum acre, commonly known as the goldmoss stonecrop, mossy stonecrop, goldmoss sedum, biting stonecrop, and wallpepper, is a perennial flowering plant in the family Crassulaceae. It is native to Europe, northern and western Asia and North Africa, but is also naturalised in North America, Japan, and New Zealand.

Rhodiola is a genus of perennial plants in the family Crassulaceae that resemble Sedum and other members of the family. Like sedums, Rhodiola species are often called stonecrops. Some authors merge Rhodiola into Sedum.
Graptopetalum bellum is a species of flowering plant in the stonecrop family Crassulaceae, native to northern Mexico. It was discovered by Alfred Lau in 1972 in the states of Chihuahua and Sonora, at an altitude of 1,460 m (4,800 ft).
Phedimus spurius, the Caucasian stonecrop or two-row stonecrop, is a species of flowering plant in the family Crassulaceae. It is still widely listed in the literature as Sedum spurium.
Hylotelephium spectabile is a species of flowering plant in the stonecrop family Crassulaceae, native to China and Korea. Its common names include showy stonecrop, iceplant, and butterfly stonecrop.
Hylotelephium is a genus of flowering plants in the stonecrop family Crassulaceae. It includes about 33 species distributed in Asia, Europe, and North America.
Rhodiola integrifolia is a species of flowering plant in the stonecrop family known by the common names ledge stonecrop, western roseroot, and king's crown. It is native to north-easternmost Russia, including Kamchatka, and western North America, where it grows in mountainous habitat in subalpine and alpine climates, including meadows, cliffs, and talus. It is a perennial herb producing a stout stem from a fleshy, branching caudex, reaching a maximum height near 30 centimeters. The fleshy leaves are alternately arranged on the stem, widely lance-shaped to oval and pointed, flat but upcurved toward the tip, reaching 2.5 centimeters long. They are green when new and age to orange, rose, or red. The inflorescence is a dense cyme of up to 50 flowers with fleshy petals in shades of bright red to deep purple. The fruits are red, rounded ovals with pointed tips.
Sedum dasyphyllum, also named Sedum burnatii and commonly known as Corsican stonecrop or thick-leaved stonecrop, is a low-growing succulent flowering plant of the genus Sedum in the family Crassulaceae.

Phedimus kamtschaticus, the orange stonecrop, is a species of flowering plant in the family Crassulaceae. It is native to China, Korea, Japan and the Russian Far East north to Chukotka, and has been introduced to the state of New York, Norway, Germany, Austria, and the Baltic States.
Rhodiola crenulata is a species of flowering plant in the family Crassulaceae, native to the Himalayas. A geophyte usually 5 to 20 cm tall, it is typically found at elevations from 2,800 to 5,600 m above sea level. Its genome has been sequenced.
Sedum humifusum, the miniature Mexican stonecrop, is a species of flowering plant in the family Crassulaceae. It is native to the Mexican states of Guanajuato, Querétaro, and Hidalgo. A creeping perennial reaching 1 cm (0.4 in), it is available from commercial suppliers, and is hardy to USDA Zone 9.
Sedum nevii, or Nevius' stonecrop, is a species of flowering plant in the family Crassulaceae. It is native to the US states of Tennessee, Alabama, and Georgia, at elevations around 1,000 m (3,300 ft). A decumbent perennial reaching 10 cm (4 in), it is usually found growing on top of mosses and lichens, themselves growing on rocky crevices, ledges, and even talus typically composed of quartzite and gneiss. Among other characters, it can be distinguished from its congeners by its red anthers, and by the pronounced lips of the adaxial suture of its follicles.
Hylotelephium ewersii, the pink Mongolian stonecrop or pink sedum, is a species of flowering plant in the family Crassulaceae. It is native to the high mountains of Asia, including the Altai, Tian Shan, and western Himalayas, and it has been introduced elsewhere, particularly to Scandinavia. A deciduous perennial reaching 15 cm (6 in), it is typically found in forests or in rocky crevices in ravines at elevations from 1,800 to 2,500 m. With its pink flowers and succulent blue‑gray leaves, and hardy to USDA zone 2, it has found use as a ground cover.
