Petunia

	Petunia ''Petunia'' is a genus of 20 species of flowering plants of South American origin. The popular flower of the same name derived its epithet from the French, which took the word , 'tobacco', from a Tupi–Guarani language. A tender perennial plant, most of the varieties seen in gardens are Hybrid (biology), hybrids (Petunia × atkinsiana, ''Petunia'' × ''atkinsiana'', also known as ''Petunia'' × ''hybrida''). Taxonomy ''Petunia'' is a genus in the Family (biology), family Solanaceae, subfamily Petunioideae. Well known members of Solanaceae in other subfamilies include Nicotiana tabacum, tobacco (subfamily Nicotianoideae), and Physalis peruviana, the cape gooseberry, tomato, potato, Atropa belladonna, deadly nightshade and Capsicum, chili pepper (subfamily Solanoideae). Some botanists place the plants of the genus ''Calibrachoa'' in the genus ''Petunia'', but this is not accepted by others. ''Petchoa'' is a hybrid genus derived from crossing ''Calibrachoa'' and ''Petunia''. Spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Petunia × Atkinsiana ''Petunia'' × ''atkinsiana'' (synonym: ''Petunia'' × ''hybrida'') is a ''Petunia'' plant "nothospecies" ( hybrid), which encompasses all hybrid species of petunia between '' P. axillaris'' and '' P. integrifolia''. Most of the petunias sold for cultivation in home gardens are this type and belong to this nothospecies. Characteristics ''Petunia'' × ''atkinsiana'' plants were originally produced by hybridisation between '' P. axillaris'' (the large white or night-scented petunia) and '' P. integrifolia'' (the violet-flowered petunia) and other members of its complex, including ''Petunia inflata''. ''P. axillaris'' bears night-fragrant, buff-white blossoms with long, thin tubes and somewhat flattened openings. The scent molecules emitted by the hybrids are generally similar to those from ''P. axillaris''. Cultivation Petunia seeds germinate in 5 to 15 days. Petunias can tolerate relatively harsh conditions and hot climates. They need at least five hours of sunlight every day. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Petunia Integrifolia ''Petunia integrifolia'' (syn. ''Petunia violacea''), the violet petunia or violetflower petunia, is a species of wild petunia with violet-colored blooms. ''Petunia integrifolia'' is native to Brazil, Argentina, Paraguay and Uruguay. ''P. integrifolia'' bears flowers approximately 1.5 inch in diameter and the plant is typically smaller and harder to cultivate than the well-known hybrid bedding ''Petunia'' now known correctly as '' Petunia × atkinsiana''. Taxonomy The species was first described as ''Salpiglossis integrifolia'' by William Jackson Hooker in 1831. It was transferred to the genus ''Petunia'' as ''P. integrifolia'' by Hans Schinz and Albert Thellung in 1915. '' Petunia inflata'' had sometimes been considered to be a subspecies of ''P. integrifolia'', but the two have different native ranges, with ''P. inflata'' growing in more northern areas. Hallucinogen ''Petunia violacea'' Lindl. has been reported to be used as a hallucinogen in Ecuador, where the pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Petunia Exserta ''Petunia exserta'' is a rare member of the genus ''Petunia'', endemic to the Serras de Sudeste in southern Brazil. First described in 1987, only fourteen plants were found in the wild during an expedition in 2007. In the wild, the plant is found growing only in shaded cracks on sandstone towers. It is the only ''Petunia'' species that is naturally pollinated by hummingbirds, and the only naturally red flowered ''Petunia'' species. Description ''Petunia exserta'' has a bright red corolla with distinctive exserted stamens and stigma, the latter which are typically associated with hummingbird pollination. It shares the erect habit, and similar corolla, pollen, and stalk attributes of '' Petunia axillaris'' and '' Petunia secreta''. The flowers have no fragrance, which is not necessary for attracting hummingbirds, who have little sense of smell. The red color is due to several anthocyanin Anthocyanins (), also called anthocyans, are solubility, water-soluble vacuole, vacuolar p ...

	Petunia Axillaris ''Petunia axillaris'', the large white petunia, wild white petunia or white moon petunia, is an annual herbaceous plant in the family Solanaceae, genus ''Petunia''. It is native to temperate South America comprising southern Brazil, parts of Argentina and Uruguay. The plant's flowers, the only white ones found in the ''Petunia'' genus, are 3 to 7 cm long. The commonly-grown garden petunia is a hybrid of ''P. axillaris'' and '' P. integrifolia''. Subspecies ''P. axillaris'' has three subspecies: '' P. a. axillaris'', ''P. a. parodii'', and '' P. a. subandina''. ''P. a. axillaris'' and ''P. a. parodii'' are found in the flat parts of the Pampas, while ''P. a. subandina'' is found in the highlands near the Andes The Andes ( ), Andes Mountains or Andean Mountain Range (; ) are the List of longest mountain chains on Earth, longest continental mountain range in the world, forming a continuous highland along the western edge of South America.
