Aeonium
''Aeonium'', the tree houseleeks, is a genus of about 35 species of succulent, subtropics, subtropical plants of the family (biology), 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 plant, 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 Leaf, leaves are typically arranged on a Basal (anatomy), 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 ''Aeonium tabuliforme, A. tabuliforme'' and ''Aeon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aeonium Arboreum
''Aeonium arboreum'', the tree aeonium, tree houseleek, or Irish rose, is a succulent, subtropical subshrub in the flowering plant family Crassulaceae. It is an invasive weed in places outside its natural distribution, for example as a garden escape throughout temperate southern Australia. Description ''Aeonium arboreum'' grows as a less branched subshrub and reaches stature heights of up to 2 metres. The more or less upright or ascending, smooth, not net-like patterned stem axes have a diameter of 1 to 3 centimetres. Their leaves are in flattened rosettes with diameters of 10 to 25 centimetres at the end of the stem axes together. Young leaves are pressed tightly together. The obovate to oblate lanceolate leaf blade is pointed toward its apex and wedge-shaped at the base. It is long, wide and 1.5 to 3 millimetres thick. The green, usually purple-colored, glossy leaf surface is almost bare. The leaf margin is set with curved eyelashes. The conical to ovate inflorescence has ...

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. ''A. tabuliforme'' requires excellent drainage, and leaf color is best in full sun. It's relatively disease-free, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeonium Undulatum
''Aeonium undulatum'' is a succulent, evergreen flowering plant in the family Crassulaceae. It is a subshrub, one of the larger species of ''Aeonium'' with an rosette of bright, glossy green 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 when after producing its yellow inflorescence, which is normally after about 5 years. ''Aeonium undulatum'' is native and 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 US, it may be grown outside in zones Zone or The Zone may refer ...

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] |
Aichryson
''Aichryson'' is a genus of about 15 species of succulent, subtropical plants, mostly native to the Canary Islands, with a few in the Azores, Madeira and Morocco. 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 ''Jovibarba'' ("beard of Jupiter") is a ...

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". Succulent plants 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 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 soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to s ...

Monanthes
''Monanthes'' is a genus of small, succulent, subtropical plants of the family Crassulaceae. The about ten species are mostly endemic to the Canary Islands and Savage Islands, with some found on Madeira. 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. Taxonomy Accepted species include: * '' Monanthes anagensis'' Praeger * ''Monanthes atlantica'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sempervivum
''Sempervivum'' (Brit. , U.S. sɛ̃mpeɹ'vivũm is a genus of about 40 species of flowering plants in the 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 genera as well. They are succulent perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via 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 live on sunny rocks and stony places in the mountain, subalpine and alpine belts. Most are hardy to US zone 4, and will ...

Macaronesia
Macaronesia (Portuguese: ''Macaronésia,'' Spanish: ''Macaronesia'') is a collection of four volcanic archipelagos in the North Atlantic, off the coasts of Africa and Europe. Each archipelago is made up of a number of List of islands in the Atlantic Ocean, Atlantic oceanic islands, which are formed by seamounts on the ocean floor whose peaks have risen above the ocean's surface. Some of the Macaronesian islands belong to Portugal, some belong to Spain, and the rest belong to Cape Verde. Politically, the islands belonging to Portugal and Spain are part of the European Union. Geologically, Macaronesia is part of the African Plate, African tectonic plate. Some of its islands – the Azores – are situated along the edge of that plate at the point where it abuts the Eurasian Plate, Eurasian and North American Plate, North American plates. In one biogeography, biogeographical system, the Cape Verde archipelago is in the Afrotropical realm while the other three archipelagos are in t ...
