Petunias
''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 hybrids ( ''Petunia'' × ''atkinsiana'', also known as ''Petunia'' × ''hybrida''). Taxonomy ''Petunia'' is a genus in the family Solanaceae, subfamily Petunioideae. Well known members of Solanaceae in other subfamilies include tobacco (subfamily Nicotianoideae), and the cape gooseberry, tomato, potato, deadly nightshade and 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''. Species Species include: Ecology Petunias are generally insect pollinated, with the exception of '' P. exserta'', which is ...

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 Mantiqueirensis
''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).

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 ...

Calibrachoa
''Calibrachoa'' is a genus of plants in the Solanaceae (nightshade) family. They are evergreen short-lived perennials and subshrubs with a sprawling habit, with small petunia-type flowers. They are found across much the same region of South America as petunias, from southern Brazil across to Peru and Chile, inhabiting scrub and open grassland. Classification ''Calibrachoa'' are closely related to ''Petunia''. However, on further examination it has been found that there are major differences in chromosomes, corresponding to external differences and fertilization factors that distinguished the two genera. ''Petchoa'' is a hybrid genus derived from crossing the genetically similar Calibrachoa and Petunia. ''Calibrachoa'' was named by Vicente Cervantes after Antonio de la Cal y Bracho, a 19th-century Mexican botanist and pharmacologist. Description ''Calibrachoa'' are small shrubs or herbaceous plants with woody shoot axis that grow annual or perennial. The leaves are ovate, ell ...

Solanaceae
Solanaceae (), commonly known as the nightshades, is a family of flowering plants in the order Solanales. It contains approximately 2,700 species, several of which are used as agricultural crops, medicinal plants, and ornamental plants. Many members of the family have high alkaloid contents, making some highly toxic, but many—such as tomatoes, potatoes, eggplants, and peppers—are commonly used in food. Originating in South America, Solanaceae now inhabits every continent on Earth except Antarctica. After the K—Pg extinction event they rapidly diversified and have adapted to live in deserts, tundras, rainforests, plains, and highlands, and taken on wide range of forms including trees, vines, shrubs, and epiphytes. Nearly 80% of all nightshades are included in the subfamily Solanoideae, most of which are members of the type genus ''Solanum''. Most taxonomists recognize six other subfamilies: Cestroideae, Goetzeoideae, Nicotianoideae, Petunioideae, Schizanthoideae, an ...
