Rhodiola
''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''. ''Rhodiola'' species grow in high-altitude and other cold regions of the Northern Hemisphere. ''Den virtuella floran'' gives the number of species as 36, the Angiosperm Phylogeny Website gives it as 90, and the ''Flora of China'' gives it as about 90, with 55 in China and 16 endemic there. ''Flora of North America'' lists only three species in the United States and Canada. Description Among the distinguishing characters of the genus are two series of stamens totaling twice the number of petals; free or nearly free petals (not joined in a tube); a stout rhizome from whose axils the flowering stems rise; and a basal rosette of leaves. This genus contains the only species of Crassulaceae that have unisexual flowers. Phytochemistry R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crassulaceae
The Crassulaceae (from Latin ''crassus'', thick), also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus ''Sedum'', and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic. Crassulaceae are mainly pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sempervivoideae
Sempervivoideae is the largest of three subfamilies in the Saxifragales family Crassulaceae, with about 20–30 genera with succulent leaves. Unlike the two smaller subfamilies, it is distributed in temperate climates. The largest genus in this subfamily is ''Sedum'', with about 470 species. Description Succulent leaved plants. Unlike the other two smaller subfamilies, which are highly derived, Sempervivoideae retain the basic features of the family Crassulaceae. The Sempervivoideae contain many familiar horticultural plants, such as ''Sedum''. Taxonomy Sempervivoideae has taxonomic priority over its synonym, Sedoideae, and is related to the other Crassulaceae subfamilies, as shown in this cladogram, although Messerschmid and colleagues (2020) state that these three subfamily clades are successive sisters, rather than Sempervivoideae being a direct sister only to Kalanchoideae. Subdivisions Six clades within Sempervivoideae have been segregated into five tribes wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhodiola Integrifolia
''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. There are several subspecies of this plant, with one, ssp. ''leedyi'', very rare and limited to a few populations in Min ...

Sedum
''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''. Well-known European species of ''Sedum'' are ''Sedum acre'', ''Sedum album'', '' Sedum dasyphyllum'', '' Sedum reflexum'' (also known as ''Sedum rupestre'') and ''Sedum hispanicum''.

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North Pole. Owing to Earth's axial tilt of 23.439281°, winter in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer lasts from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that affect many factors within the north coast. Such events include El Niño–Southern Oscillation. Trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents, which flow westward due to the Coriolis e ...
