Aeonium
''Aeonium'', the tree houseleeks, is a genus of about 35 species of succulent, subtropical plants of the family Crassulaceae. Many species are popular in horticulture. The genus name comes from the ancient Greek αἰώνιος / aiōnios (ageless). While most of them are native to the Canary Islands, some are found in Madeira, Cape Verde, Morocco, in East Africa (Ethiopia, Somalia, Uganda, Tanzania and Kenya) and Yemen. Description The succulent leaves are typically arranged on a basal stem, in a dense, spreading rosette. A feature which distinguishes this genus from many of its relatives is the manner in which the flowers bear free petals, and are divided into 6 or 12 sections. Each rosette produces a central inflorescence only once, and then dies back (though it will usually branch or offset to produce ensuing rosettes). Low-growing ''Aeonium'' species are '' A. tabuliforme'' and '' A. smithii''; large species include '' A. arboreum and'' '' A. valverdense ...

Crassulaceae
The Crassulaceae (, from Latin ''crassus'', thick), also known as the crassulas, the stonecrops or the orpine family, are a diverse Family (biology), family of dicotyledon angiosperms primarily characterized by succulent leaves and a form of photosynthesis known as crassulacean acid metabolism (CAM), in which plants photosynthesize in the daytime and exchange gases during the cooler temperatures of the night. The blossoms of crassulas generally have five floral parts. Crassulaceae are usually herbaceous, though there are some subshrubs, and relatively few trees or aquatic plants. The Crassulaceae is a medium-sized, monophyletic family in the core eudicots clade, along with 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''—distributed over three subfamilies. Members of the Crassulaceae are found worldwide, though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeonium Tabuliforme
''Aeonium tabuliforme'', the flat-topped aeonium or saucer plant, is a species of succulent plant in the family Crassulaceae, native and endemic to Tenerife in the Canary Islands. It is low-growing, typically reaching about 5 cm high but up to 45 cm in diameter. It grows on moist, north-facing cliffs and ledges at low altitude. A mass of fleshy, hairy, bright green leaves in flat rosettes is produced on short unbranched stems, often on vertical surfaces. This species is short-lived and dies after flowering. Plants often take 3–4 years to flower, at which point they produce a tall (40–60 cm) raceme of yellow flowers. The Latin specific epithet ''tabuliforme'' means "flat" (literally "table shaped"). This plant, which may be either biennial or perennial, is grown under glass in temperate regions. It has gained the Royal Horticultural Society's Award of Garden Merit. It requires excellent drainage, and leaf color is best in full sun. It is relatively disease-free ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeonium Undulatum
''Aeonium undulatum'' is a succulent plant, succulent, evergreen flowering plant in the family Crassulaceae. It is a subshrub, one of the larger species of ''Aeonium'' with an rosette (botany), rosette of bright, glossy green Leaf, leaves often over a metre from the ground on a single, unbranched stem. Other rosettes do not branch off this stem (normally) but grow from the bottom, unlike most aeoniums. The plant is monocarpic so the flowering stem will die after producing its yellow inflorescence, which is normally after about 5 years. ''Aeonium undulatum'' is native plant, native and endemism, endemic to Gran Canaria in the Canary islands. The Latin specific epithet ''undulatum'' means "wavy", and refers to the leaf shape. The common name "saucer plant" is applied to this and other plants of a similar habit. In temperate regions this plant may be grown under glass, in a suitable cactus compost. It prefers full sun to part shade and requires excellent drainage. In the United ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aichryson
''Aichryson'' is a genus of 16 species of succulent, subtropical plants, native to the Canary Islands, Azores, and Madeira. The species of ''Aichryson'' are not frost-resistant. They are related to ''Sempervivum, Jovibarba, Greenovia, Aeonium'' and ''Monanthes'', readily seen in their similar flowers. The genus name comes from a contraction of the Greek "aei" (always) and "chrysos" (gold). Several species are cultivated as ornamental plants. The hybrid cultivar ''Aichryson'' × ''aizoides'' var. ''domesticum'' 'Variegatum' is a recipient of the Royal Horticultural Society's Award of Garden Merit. Taxonomy Recent phylogenetic studies of Crassulaceae indicate that ''Aichryson'' is closely related to ''Monanthes'' and ''Aeonium'' (both genera are also largely endemic to the Canary Islands). Two other genera of Crassulaceae that have many-parted (polymerous) flowers (''Sempervivum'' and '' Jovibarba'') are not closely related to the three Canary Island genera.Mort et al. (2002) ...

Succulent
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulents may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as '' Glottiphyllum semicyllindricum'' and '' Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs (caudex) may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky or sandy soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monanthes
''Monanthes'' is a genus of small, succulent, subtropical plants of the family Crassulaceae. Most species in the genus are endemic to the Canary Islands, with one species also endemic to the Savage Islands and another to the High Atlas mountains of Morocco. Its center of diversity is Tenerife, with seven species occurring on this island. On Fuerteventura and Lanzarote, only ''M. laxiflora'' occurs. ''Monanthes'' is a rare example where a species re-colonizes the continent from an island, after their ancestors have colonized the island from the continent. ''Monanthes'' are not frost-resistant. They are linked with the genera ''Sempervivum'', '' Greenovia'', '' Aichryson'' and ''Aeonium'', which is obvious from their similar flowers. Species of ''Monanthes'' differ considerably in life- and growth-form. ''M. icterica'', which is also genetically quite distant to other ''Monanthes'' species, is annual, while the other species are perennial In horticulture, the term perennial (' ...

Sempervivum
''Sempervivum'' () is a genus of about 40 species of flowering plants in the family (biology), family Crassulaceae, commonly known as houseleeks. Other common names include liveforever (the source of the taxonomical designation ''Sempervivum'', literally "always/forever alive") and hen and chicks, a name shared with plants of other Hen and Chicken plant, genera as well. They are succulent plant, succulent perennial plant, perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offset (botany), offsets, and several species are valued in cultivation as groundcover for dry, sunny locations. Habitat Houseleeks exist from Morocco to Iran, through the mountains of Iberia, the Alps, Carpathians, Balkan mountains, Turkey, the Armenian mountains, in the northeastern part of the Sahara Desert, and the Caucasus. Their ability to store water in their thick leaves allows them to Lithophyte, live on sunny rocks and stony places in the moun ...
