Nicotiana Alata
''Nicotiana alata'' is a species of tobacco. It is called jasmine tobacco, sweet tobacco, winged tobacco, ''tanbaku'', and Persian tobacco. ''Nictoiana alata'' is mainly grown as an ornamental plant; numerous cultivars and hybrids are derived from it. In Iran, narghila tobacco is sometimes produced from ''N. alata''; it is not chopped like cigarette tobacco, but broken up by hand. *Flowering season: Summer to fall *Light requirements: Sun to partial shade *Flower color: Lime green, maroon red, white, yellow, pink, and crimson *Height: 30 to 60 cm 2 to 24 inches*Spacing: 30 to 40 cm 2 to 14 inches*Comments: Low drought tolerance Has a lovely fragrance in the evening to night. Most varieties bloom late-afternoon to evening. Seedlings do best when gradually introduced to outdoor environment over the course of a week. Plants tend to self-sow. (Color may be the original or occasionally several colors on one plant). Deadhead A Deadhead or Dead Head is a fan of the Am ...

Johann Heinrich Friedrich Link
Johann Heinrich Friedrich Link (2 February 1767 – 1 January 1851) was a German naturalist and botanist. Biography Link was born at Hildesheim as a son of the minister August Heinrich Link (1738–1783), who taught him love of nature through collection of 'natural objects'. He studied medicine and natural sciences at the Hannoverschen Landesuniversität of Göttingen, and graduated as MD in 1789, promoting on his thesis ''"Flora der Felsgesteine rund um Göttingen"'' (Flora of the rocky beds around Göttingen). One of his teachers was the famous natural scientist Johann Friedrich Blumenbach (1752–1840). He became a private tutor (''Privatdozent'') in Göttingen. In 1792 he became the first professor of the new department of chemistry, zoology and botany at the University of Rostock. During his stay at Rostock, he became an early follower of the antiphlogistic theory of Lavoisier, teaching about the existence of oxygen instead of phlogiston. He was also a proponent of the ...

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 any 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, which is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending 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 hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iran
Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmenistan to the north, by Afghanistan and Pakistan to the east, and by the Gulf of Oman and the Persian Gulf to the south. It covers an area of , making it the 17th-largest country. Iran has a population of 86 million, making it the 17th-most populous country in the world, and the second-largest in the Middle East. Its largest cities, in descending order, are the capital Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz. The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great fo ...

Narghila
A hookah ( Hindustani: (Nastaleeq), (Devanagari), IPA: ; also see other names), shisha, or waterpipe is a single- or multi-stemmed instrument for heating or vaporizing and then smoking either tobacco, flavored tobacco (often ''muʽassel''), or sometimes cannabis, hashish and opium. The smoke is passed through a water basin—often glass-based—before inhalation. The major health risks associated with smoking tobacco, cannabis, opium and other drugs through a hookah include exposure to toxic chemicals, carcinogens and heavy metals that are not filtered out by the water, alongside those related to the transmission of infectious diseases and pathogenic bacteria when hookahs are shared. Hookah and waterpipe use is a global public health concern, with high rates of use in the populations of the Middle East and North Africa as well as in young people in the United States, Europe, Central Asia, and South Asia. The hookah or waterpipe was invented by Abul-Fath Gilani, a Persian p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deadheading (flowers)
Deadheading is the horticultural practice of removing spent flowers from ornamental plants. Deadheading is a widespread form of pruning, since fading flowers are not as appealing and direct a lot of energy into seed development if pollinated. The goal of deadheading is thus to preserve the attractiveness of the plants in beds, borders, containers and hanging baskets, as well as to encourage further blooming. Deadheading flowers with many petals, such as roses, peonies, and camellias prevents them from littering. Deadheading can be done with finger and thumb or with pruning shears, knife, or scissors. Ornamental plants that do not require deadheading are those that do not produce a lot of seed or tend to deadhead themselves. These include lobelias, salvias, and fuchsias. Deadheading is undesirable if the plant's seed is enjoyed by birds, as is the case with many species from the family Asteraceae. Likewise, if the plant bears attractive seeds or fruits, deadheading is normally av ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobacco
Tobacco is the common name of several plants in the genus '' Nicotiana'' of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is ''N. tabacum''. The more potent variant ''N. rustica'' is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death. Etymology The English word ''tobacco'' originates from the Spanish word "tabaco ...
