Asphodelaceae Genera
Asphodelaceae is a Family (biology), family of flowering plants in the Order (biology), order Asparagales. Such a family has been recognized by most taxonomists, but the Circumscription (taxonomy), circumscription has varied widely. In its current Circumscription (taxonomy), circumscription in the APG IV system, it includes about 40 Genus, genera and 900 known species. The type genus is ''Asphodelus''. The family has a wide, but scattered, Range (biology), distribution throughout the tropics and temperate zones; for example, ''Xanthorrhoea'' is endemism, endemic to Australia, while the ''Aloe, Aloes'' are unique to Africa and parts of the Arabian Peninsula. Many of the family's genera are Horticulture, cultivated as Ornamental plant, ornamentals, with some being highly collectible and sought-after, such as ''Haworthia'' and ''Gasteria'', as well as their Hybrid (biology), intergeneric hybrids with ''Aloe'' (''× Gasteraloe, x Gasteraloe'', x ''Gastorthia'', x ''Haworthaloe'', etc ...

Xanthorrhoea
''Xanthorrhoea'' () is a genus of about 30 species of Succulent plant, succulent flowering plants in the family Asphodelaceae. They are Endemism, endemic to Australia. Common names for the plants include grasstree, grass gum-tree (for resin-yielding species), kangaroo tail, balga (Western Australia), yakka (South Australia), yamina (Tasmania), and black boy (or "blackboy"). The most common species is ''Xanthorrhoea australis'', and some of these names are applied specifically to this species. Description All species in the genus are Perennial plant, perennials and have a secondary growth, secondary thickening meristem in the stem. Many, but not all, species develop an above ground stem. The stem may take up to twenty years to emerge. Plants begin as a crown of rigid grass-like leaves, the caudex slowly growing beneath. The main stem or branches continue to develop beneath the crown. This is rough-surfaced, built from accumulated leaf-bases around the secondarily thickened trunk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aloe Vera
''Aloe vera'' () is a succulent plant species of the genus ''Aloe''. It is widely distributed, and is considered an invasive species in many world regions. An evergreen perennial plant, perennial, it originates from the Arabian Peninsula, but also grows wild in tropical, semi-tropical, and arid climates around the world. It is cultivated for commercial products, mainly as a topical medication, topical treatment used over centuries. The species is considered attractive for decorative purposes, and is often used indoors as a potted plant. The leaves of ''Aloe vera'' contain significant amounts of the polysaccharide gel acemannan, which can be used for topical purposes. The leaves also contain aloin, which is a toxicity, toxic compound. ''Aloe vera'' products are typically made from the gel. ''Aloe vera'' acemannan may be used in skin lotions, cosmetics, ointments and gels for minor burns, skin Abrasion (medicine), abrasions, insect bites, and windburn. Oral ingestion of aloe ve ...

Floriculture
Floriculture (from ) is the study of the efficient production of the plants that produce showy, colorful flowers and foliage for human enjoyment in human environments. It is a commercially successful branch of horticulture and agriculture found throughout the world. Efficient production practices have been developed over the years, for the hundreds of plant taxa used in the floral industry, increasing the overall knowledge of whole plant biology. Plant breeding and selection have produced tens of thousands of new genotypes for human use. Overview Flowers are an important part of human society that are often used at times of joy and sadness, and as a part of everyday life. Flowers and plants may be indoors in a sunny window, as part of the landscape in the front yard or on the patio or deck in the back yard. People have been studying flowers and plants and their interaction with humans and how to produce these flowers and plants so all humans can enjoy them. Floriculture scie ...

Commerce
Commerce is the organized Complex system, system of activities, functions, procedures and institutions that directly or indirectly contribute to the smooth, unhindered large-scale exchange (distribution through Financial transaction, transactional processes) of goods and services, goods, services, and other things of value at the right time, place, quantity, Quality (business), quality and price through various Distribution (marketing)#Channels and intermediaries, channels among the original Economic production, producers and the final consumers within local, regional, national or international economies. The diversity in the distribution of natural resources, differences of human needs and wants, and division of labour along with comparative advantage are the principal factors that give rise to commercial exchanges. Commerce consists of trade and aids to trade (i.e. auxiliary commercial services) taking place along the entire supply chain. Trade is the exchange of goods (includi ...

× Gasteraloe
× ''Gasteraloe'' (× ''Gastrolea'') is a nothogenus of hybrid plants, from crosses between species in the genera ''Gasteria'' and ''Aloe'' or '' Aristaloe''. Since the plants originated as hybrids, and accordingly are not true species in the sense of formal Plant taxonomy, Gasteraloe is not technically a true genus, but a "nothogenus", whether the plants' gametes are sterile or not. Description × ''Gasteraloe'' hybrids are typically stemless or almost stemless. Their succulent leaves, which are usually spotted or marked and have toothed margins, form rosettes. '' Gonialoe variegata'' and '' Aristaloe aristata'' are especially commonly used for these hybrids, as they are far more amenable to hybridization with gasterias than most other "aloes". List of known hybrids Among the range of × ''Gasteraloe'' hybrids that are known so far are: * × ''Gasteraloe bedinghausii'' = '' Aristaloe aristata'' × '' Gasteria disticha'' * × ' ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Gasteria
''Gasteria'' is a genus of succulent plants, native to South Africa and the far south-west corner of Namibia. Naming The genus is named for its stomach-shaped flowers (''"gaster"'' is Greek for "stomach") that result from the swollen base on the corolla. Common names include ''ox-tongue'', ''cow-tongue'', ''lawyer's tongue'' and, occasionally, ''mother-in-law's tongue''. Description Gasterias are recognisable from their thick, hard, succulent "tongue-shaped" leaves. These are either in two opposite ranks (distichous), or in various distinctive spiral arrangements. Their inflorescence is also unique, with their curved, stomach-shaped flowers, which hang from inclined racemes. Distribution The species of this genus are mostly native to the Eastern Cape Province, South Africa, where the bulk of the species occur – especially in the small area between Makhanda and Uniondale which enjoys rainfall throughout the year. However, the distribution of several species extends widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthia
''Haworthia'' is a large genus of small succulent plants endemic to Southern Africa (Mozambique, Namibia, Lesotho, Eswatini and South Africa). Like aloes and gasteria they are members of the Family (biology), subfamily Asphodeloideae and they generally resemble miniature aloes, except in their flowers, which are distinctive in appearance. They are popular garden and container plants. These plants were discovered by Henri Auguste Duval (1777-1814) in 1809. The genus name is derived from Adrian Hardy Haworth, Adrian Hardy Haworth’s (1767-1833) name, a botanist and avid succulent collector. Description and characteristics ''Haworthias'' are small succulent plants, forming rosettes of leaves from to exceptionally in diameter, depending on the species. These rosettes are usually stemless but in some species stems reach up to . The inflorescences of some species may exceed in height. The plants can grow solitary or can be clump-forming. Many species have firm, tough, fleshy l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Plant
Ornamental plants or ''garden plants'' are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost all types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents, aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and ''foliage plants''. The cultivation of ornamental plants comes under floriculture and tree nurseries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horticulture
Horticulture (from ) is the art and science of growing fruits, vegetables, flowers, trees, shrubs and ornamental plants. Horticulture is commonly associated with the more professional and technical aspects of plant cultivation on a smaller and more controlled scale than agronomy. There are various divisions of horticulture because plants are grown for a variety of purposes. These divisions include, but are not limited to: propagation, arboriculture, landscaping, floriculture and turf maintenance. For each of these, there are various professions, aspects, tools used and associated challenges -- each requiring highly specialized skills and knowledge on the part of the horticulturist. Typically, horticulture is characterized as the ornamental, small-scale and non-industrial cultivation of plants; horticulture is distinct from gardening by its emphasis on scientific methods, plant breeding, and technical cultivation practices, while gardening, even at a professional level, tends ...

Arabian Peninsula
The Arabian Peninsula (, , or , , ) or Arabia, is a peninsula in West Asia, situated north-east of Africa on the Arabian plate. At , comparable in size to India, the Arabian Peninsula is the largest peninsula in the world. Geographically, the Arabian Peninsula comprises Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE) and Yemen, as well as southern Iraq and Jordan. The largest of these is Saudi Arabia. In the Roman era, the Sinai Peninsula was also considered a part of Arabia. The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and south-west, the Persian Gulf and the Gulf of Oman to the north-east, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Ocean to the south-east. The peninsula plays a critical geopolitical role in the Arab world and globally due to its vast reserves of petroleum, oil and natural gas. Before the mod ...
