Begonia is a genus of perennial flowering plants in the family Begoniaceae. The genus contains more than 2,000 different plant species. The Begonias are native to moist subtropical and tropical climates. Some species are commonly grown indoors as ornamental houseplants in cooler climates. In cooler climates some species are cultivated outside in summertime for their bright colorful flowers, which have sepals but no petals.
Begoniaceae is a family of flowering plants with two genera and about 1825 species occurring in the subtropics and tropics of both the New World and Old World. All but one of the species are in the genus Begonia. There have been many recent discoveries of species in the genus Begonia, such as Begonia truncatifolia which is endemic to San Vincente, Palawan. B. truncatifolia is smaller in size than other species of the genus Begonia and this new species is proposed Critically Endangered by standards set by the IUCN. The only other genus in the family, Hillebrandia, is endemic to the Hawaiian Islands and has a single species. Phylogenetic work supports Hillebrandia as the sister taxon to the rest of the family. The genus Symbegonia was reduced to a section of Begonia in 2003, as molecular phylogenies had shown it to be derived from within that genus. Members of the genus Begonia are well-known and popular houseplants.
Symphyotrichum ericoides, known as white heath aster, frost aster, or heath aster, is a species of flowering plant in the family Asteraceae native to much of central and eastern North America. It has been introduced to parts of Europe and western Asia.
Begonia grandis, the hardy begonia, is a species of flowering plant in the family Begoniaceae. This herbaceous perennial has alternate, simple leaves on arching stems. The flowers are pink or white, borne in dichotomously branching cymes from late summer through fall in USDA U.S. Hardiness Zone 7. As the common name "hardy begonia" implies, it is winter hardy in some temperate regions.
Symphyotrichum lanceolatum is a species of flowering plant in the family Asteraceae native to North America. Common names include panicled aster, lance-leaved aster, and white panicled aster. It is a perennial, herbaceous plant that may reach 1.5 meters tall or more, sometimes approaching 2 meters. The lance-shaped leaves are generally hairless but may feel slightly rough to the touch on the top because of tiny bristles. The flowers grow in clusters and branch in panicles. They have 16–50 white ray florets that are up to 14 millimeters long and sometimes tinged pink or purple. The flower centers consist of disk florets that begin as yellow and become purple as they mature.
Begonia foliosa is a species of flowering plant in the family Begoniaceae, native to Colombia and Venezuela. It is a shrublike begonia growing to 1 metre (3.3 ft), bearing succulent, pendent stems 45 centimetres (18 in) long, thickly clothed with glossy oval green leaves, and producing panicles of small white flowers. The variety commonly cultivated is B. foliosa var. miniata with pink or red flowers. As it does not tolerate temperatures below 0 °C (32 °F), in temperate regions it requires winter protection.
Symphyotrichum subulatum, commonly known as eastern annual saltmarsh aster or, in Britain and Ireland where it is naturalized, annual saltmarsh aster, is an annual plant in the family Asteraceae native to the eastern United States and the Gulf Coast to Texas. The species grows primarily in coastal salt marshes, although in the Ozarks it occurs as a non-marine weedy variety.
Iris sikkimensis is a plant species in the genus Iris, it is also in the subgenus Iris and in the section Pseudoregelia. It is a rhizomatous perennial, from Sikkim. It has pale green or light green thin leaves, slender stem, 2 or 3 lilac or purple flowers, with a white beard with orange tips. It is thought to be a hybrid of Iris hookeriana and Iris kumaonensis.
Begonia cucullata, also known as wax begonia and clubed begonia, is a species of the Begoniaceae that is native to South American countries of Argentina, Brazil, Paraguay, and Uruguay. A common garden plant and part of the section Begonia, it was described in 1805 by Carl Ludwig Willdenow (1765–1812). The specific epithet "cucullata" means "resembling a hood" or "hooded".
Begonia dregei, the maple leaf begonia or grape-leaf begonia, is a species of flowering plant in the genus Begonia native to South Africa. It has gained the Royal Horticultural Society's Award of Garden Merit.
Begonia rex, the king begonia, is a species of flowering plant in the family Begoniaceae. It is found from Arunachal Pradesh to southeast China, and has been introduced to Bangladesh, Cuba, and Hispaniola. It is a parent to over 500 cultivars in the Begonia Rex Cultorum Group of houseplants. Other parents in the multitude of crosses made during the creation of the Group include Begonia annulata, B. cathayana, B. decora, B. diadema, B. dregei, B. grandis, B. hatacoa, B. palmata, and B. xanthina.
Begonia heracleifolia, the star begonia, is a species of flowering plant in the family Begoniaceae. It is native to Mexico and northern Central America, and has been introduced to Cuba, Hispaniola, Puerto Rico, and Trinidad and Tobago. A widespread species that is adapted to drought, it possesses considerable genetic and morphological variation, particularly in leaf shape and patterning.
Begonia goegoensis, the fire-king begonia, is a species of flowering plant in the family Begoniaceae, native to Sumatra. In 1882 it was exhibited by Veitch and Sons and received a first class certificate from the Royal Horticultural Society. Valued for its striking red-backed leaves, it can be propagated from cuttings, although seeds may do better.
Begonia bogneri is a species of flowering plant in the family Begoniaceae, native to a single 1 ha locality on the Masoala Peninsula of Madagascar. Uniquely among begonias, it has linear, grass-like leaves. It does well in terrariums.
Begonia ulmifolia, the elm-leaf begonia, is a species of flowering plant in the family Begoniaceae. It is native to South America; Trinidad and Tobago, Venezuela, the Guianas, and eastern Brazil, and introduced to Mauritius, Réunion, and the Seychelles in the Indian Ocean. Cultivated for its ornamental foliage more than its flowers, it is suitable for green roofs in hot and humid areas.
Begonia bowerae, the eyelash begonia, is a species of flowering plant in the family Begoniaceae, native to Oaxaca and Chiapas states of Mexico. A popular houseplant, a number of cultivars are available.
Begonia hatacoa is a species of flowering plant in the family Begoniaceae, native to Tibet, Nepal, the eastern Himalayas, Assam, Bangladesh, Myanmar, Thailand, and Vietnam. Its best-known cultivar is 'Silver'.
Begonia fuchsioides, the fuchsia begonia, is a species of flowering plant in the family Begoniaceae. It is native to Ecuador, Colombia, and western Venezuela, and has been introduced to Hawaii and Réunion. A small bush reaching 2 ft (60 cm), it is hardy to USDA zone 10a.
Begonia manicata is a species of flowering plant in the family Begoniaceae, native to Mexico and Central America. The cultivar 'Aureo-maculata' is called the leopard begonia.
