'''''Sedum''''' is a large [[genus]] of [[flowering plant]]s in the family [[Crassulaceae]], members of which are commonly known as '''stonecrops'''. It contains around 400 species of leaf [[succulents]] that are found throughout the [[Northern Hemisphere]], varying from [[Annual plant|annual]] and creeping [[Herbaceous plant|herbs]] to [[shrub]]s. The plants have water-storing leaves. The flowers usually have five [[petals]], seldom four or six. There are typically twice as many [[stamen]]s as [[petals]].
 +
 +
Well known European ''Sedums'' are ''[[Sedum acre]]'', ''[[Sedum album]]'', ''[[Sedum dasyphyllum]]'', ''[[Sedum reflexum]]'' (also known as ''Sedum rupestre'') and ''[[Sedum hispanicum]]''.
 +
 +
Many sedums are [[Horticulture|cultivated]] as [[garden]] plants, due to their interesting and attractive appearance and hardiness. The various species differ in their requirements; some are cold-hardy but do not tolerate heat, some require heat but do not tolerate cold.

Plants glabrous or glandular-pubescent, fleshy, erect or decumbent, sometimes cespitose or moss-like: lvs. very variable, opposite, alternate or whorled, entire or serrate: fls. cymose in a few axils and solitary, white, yellow, or rose, rarely red or blue, hermaphrodite or unisexual by abortion; calyx 4-5-lobed; petals 4-5 (rarely 6-7), free; stamens 8-10 (rarely 12-14); ovary 4-5-carpelled: follicles 4-5, free, many- or few-seeded.— About 280 species, mostly natives of the temperate and colder regions of the northern hemisphere. The hardy sedums are monographed, from a horticultural point of view, by M. T. Masters in Gardener's Chronicle for 1878. Masters' descriptions and treatment have been partially followed in the present revision. The variability of the lf. is very noticeable both in thickness and breadth, some being thick and terete, others flat and thin, though all of them tending toward fleshy. Some are quite linear and from that they range to nearly 1 1/2 in. broad. The margin is also variable from entire to deeply dentate. The synonymy of the species is much involved and in some groups, especially the Telephium group, the specific delimitation is very uncertain; in fact the whole genus needs monographic study. The present key is an attempt to differentiate the more prominent forms as they occur in horticulture and is based in part on literature and in part on herbarium specimens. It is unfortunately not altogether satisfactory but may prove of some value in separating the species. {{SCH}}

Sedums are of the easiest culture. As a rule, they prefer sandy soil, and are very averse to a wet position in winter. Some are useful plants for carpeting poor and sandy waste places where few other things will grow. The little yellow-flowered plant with pulpy foliage that spreads in nearly every cemetery is Sedum acre. Sedums are also general favorites in all forms of rock-gardening. They are much used for carpet-bedding, especially the kinds with mealy or glaucous foliage, and those with various metallic shades of purple. In the hardy border, the more robust and bushy kinds, like S. maximum and S. spectabile, are preferred, though any of the lower-growing kinds are suitable for edgings and any of the evergreen kinds are welcome in winter when the hardy border shows few other bits of color or signs of life. As a rule, sedums like the sun, but a few of the species may help to solve the difficult problem of carpeting the ground underneath the trees where the soil is dry and shaded. Sedums are also favorites for baskets and vases, especially the kinds with trailing stems and minute leaves. For greenhouse decoration, S. spectabile is the favorite, as it is perhaps the showiest of the genus. It may be had in flower at any season of the year and remains in bloom a long time. It is also one of the favorite sedums for window-sills, balconies, and housetops, especially in crowded cities. Sedum acre, however, is everybody's plant. A piece of it is often the only pleasant sight in an ugly city alley. Sedums can be propagated by seeds, but they are easily multiplied by the young offsets. These rosettes are somewhat bulb-like in nature and sedums could probably be propagated if it were worth while by using each leaf of a rosette.{{SCH}}

Sedum is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. It contains around 400 species of leaf succulents that are found throughout the Northern Hemisphere, varying 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.

Well known European Sedums are Sedum acre, Sedum album, Sedum dasyphyllum, Sedum reflexum (also known as Sedum rupestre) and Sedum hispanicum.

Many sedums are cultivated as garden plants, due to their interesting and attractive appearance and hardiness. The various species differ in their requirements; some are cold-hardy but do not tolerate heat, some require heat but do not tolerate cold.


Read about Sedum in the Standard Cyclopedia of Horticulture 

Sedum (Latin, sedes, to sit: the plants fix themselves on rocks and walls). Crassulaceae. Succulent herbs, rarely subshrubs, mostly hardy and perennial, useful for rockeries and one species, S. spectabile, a frequent showy border plantCH.

Plants glabrous or glandular-pubescent, fleshy, erect or decumbent, sometimes cespitose or moss-like: lvs. very variable, opposite, alternate or whorled, entire or serrate: fls. cymose in a few axils and solitary, white, yellow, or rose, rarely red or blue, hermaphrodite or unisexual by abortion; calyx 4-5-lobed; petals 4-5 (rarely 6-7), free; stamens 8-10 (rarely 12-14); ovary 4-5-carpelled: follicles 4-5, free, many- or few-seeded.— About 280 species, mostly natives of the temperate and colder regions of the northern hemisphere. The hardy sedums are monographed, from a horticultural point of view, by M. T. Masters in Gardener's Chronicle for 1878. Masters' descriptions and treatment have been partially followed in the present revision. The variability of the lf. is very noticeable both in thickness and breadth, some being thick and terete, others flat and thin, though all of them tending toward fleshy. Some are quite linear and from that they range to nearly 1 1/2 in. broad. The margin is also variable from entire to deeply dentate. The synonymy of the species is much involved and in some groups, especially the Telephium group, the specific delimitation is very uncertain; in fact the whole genus needs monographic study. The present key is an attempt to differentiate the more prominent forms as they occur in horticulture and is based in part on literature and in part on herbarium specimens. It is unfortunately not altogether satisfactory but may prove of some value in separating the species. CH

Sedums are of the easiest culture. As a rule, they prefer sandy soil, and are very averse to a wet position in winter. Some are useful plants for carpeting poor and sandy waste places where few other things will grow. The little yellow-flowered plant with pulpy foliage that spreads in nearly every cemetery is Sedum acre. Sedums are also general favorites in all forms of rock-gardening. They are much used for carpet-bedding, especially the kinds with mealy or glaucous foliage, and those with various metallic shades of purple. In the hardy border, the more robust and bushy kinds, like S. maximum and S. spectabile, are preferred, though any of the lower-growing kinds are suitable for edgings and any of the evergreen kinds are welcome in winter when the hardy border shows few other bits of color or signs of life. As a rule, sedums like the sun, but a few of the species may help to solve the difficult problem of carpeting the ground underneath the trees where the soil is dry and shaded. Sedums are also favorites for baskets and vases, especially the kinds with trailing stems and minute leaves. For greenhouse decoration, S. spectabile is the favorite, as it is perhaps the showiest of the genus. It may be had in flower at any season of the year and remains in bloom a long time. It is also one of the favorite sedums for window-sills, balconies, and housetops, especially in crowded cities. Sedum acre, however, is everybody's plant. A piece of it is often the only pleasant sight in an ugly city alley. Sedums can be propagated by seeds, but they are easily multiplied by the young offsets. These rosettes are somewhat bulb-like in nature and sedums could probably be propagated if it were worth while by using each leaf of a rosette.CH

Mex. —S. albidum, Hort., is offered in the trade as a form growing 6 in. high, with white fls. —S. allantoides, Rose. Perennial, 8-12 in. high, woody below: lvs. almost at right angles to the st., terete, clavate and somewhat bowed, glaucous: fls. greenish white, in an open terminal panicle; sepals ovate, acute; petals lanceolate, acute. Mex. —S. atrosanguineum, Hort., is offered in the trade. —S. bellum, Rose (S. farinosum, Rose, not Lowe). Perennial plants, at first forming dense elongated rosettes: fl. -st. weak, ascending or spreading: lvs. flat but thickish spatulate: infl. a broad open cyme; petals white, spreading, lanceolate. Mex. In its wild state this species grows on cliffs among mosses. It has been in cult. in Washington since 1906, and deserves a place in every good succulent collection. —S. Braunii, Hort., is offered. —S. Brownii, Hort., is offered in the trade. — S. calabricum, Ten., is a name without description applied to some Italian species which is offered in the trade. —S. coccineum Hort., not Royle, is a name mentioned in horticulture; possibly it is S. stoloniferum var. coccineum. —S.
