Begonia is a genus in the flowering plant family Begoniaceae.
With fraction 1500+ species, Begonia is one of the ten largest angiosperm genera. The species are terrestrial (sometimes epiphytic) herbs or undershrubs and occur in subtropical and tropical moist climates, in South and Central America, Africa and southern Asia. Terrestrial species in the wild are commonly upright-stemmed, rhizomatous, or tuberous. The plants are monoecious, with unisexual male and female flowers occurring separately on the same plant, the male containing numerous stamens, the female having a large inferior ovary and two to four branched or twisted stigmas. In most species the fruit is a winged capsule containing numerous minute seeds, although baccate fruits are also known. The leaves, which are often large and variously marked or variegated, are usually asymmetric (unequal-sided).
Because of their sometimes showy flowers of white, pink, scarlet or yellow color and often attractively marked leaves, many species and innumerable hybrids and cultivars are cultivated. Most species can frequently be hybridized with each other and this has led to an enormous number of cultivars thus allowing hybrids to have characteristics of more than one group. The genus name coined by Charles Plumier French patron of botany honors Michel Bégon, a former governor of the french colony of Haiti.
The different groups of begonias have different cultural requirements but most species come from tropical regions and therefore they and their hybrids require warm temperatures. Most are forest understory plants and require bright shade; few will tolerate full sun, especially in warmer climates. In general, begonias require a well-drained growing medium that is neither constantly wet nor allowed to dry out completely. Many begonias will grow and flower year-round but tuberous begonias usually have a dormant period, during which the tubers can be stored in a cool and dry place.
Begonias of the semperflorens group are frequently grown as bedding plants outdoors. A recent group of hybrids derived from this group is marketed as "Dragonwing Begonias"; they are much larger both in leaf and in flower. Tuberous begonias are frequently used as container plants. Although most Begonia species are tropical or subtropical in origin, the Chinese species B. grandis is hardy to USDA hardiness zone 6 and is commonly known as the "hardy begonia". Most begonias can be grown outdoors year-round in subtropical or tropical climates, but in temperate climates begonias are grown outdoors as annuals, or as house or greenhouse plants.
Most begonias are easily propagated by division or from stem cuttings. In addition, many can be propagated from leaf cuttings or even sections of leaves, particularly the members of the rhizomatous and rex groups
They are evergreen shrubs and small trees 2–20 m tall. The leaves are alternately arranged, simple, thick, serrated, usually glossy, and 3–17 cm long. The flowers are large and conspicuous, 1–12 cm diameter, with (in natural conditions) 5–9 petals; colour varies from white to pink and red, and yellow in a few species. The fruit is a dry capsule, sometimes subdivided into up to 5 compartments, each compartment containing up to 8 seeds.
The genus is generally adapted to acidic soils, and does not grow well on chalk or other calcium-rich soils. Most species also have a high rainfall requirement and will not tolerate drought. Some Camellias have been known to grow without much rainfall.
Camellia sinensis is of major commercial importance because tea is made from its leaves. Tea oil is a sweet seasoning and cooking oil made by pressing the seeds of Camellia sinensis or Camellia oleifera.
Many other camellias are grown as ornamental plants for their flowers; about 3,000 cultivars and hybrids have been selected, many with double flowers. Camellia japonica (often simply called Camellia) is the most prominent species in cultivation, with over 2,000 named cultivars.
Camellias have a slow growth rate. Typically they will grow about 30 centimetres a year until mature although this varies depending on variety and location.
Fuchsia is a genus of flowering plants, mostly shrubs and can grow long shoots, which were identified by Charles Plumier in the late-17th century, and named by Plumier in 1703 after the German botanist Leonhart Fuchs (1501–1566).The English vernacular name Fuchsia is the same as the scientific name.There are about 100–110 species of Fuchsia. The great majority are native to South America, but with a few occurring north through Central America to Mexico, and also several from New Zealand, and Tahiti. Most fuchsias are shrubs from 0.2–4 m (8 in-13 ft) tall, but one New Zealand species, Kotukutuku (Fuchsia excorticata), is unusual in the genus in being a tree, growing up to 12–15 m (39-49 ft) tall.
Fuchsia leaves are opposite or in whorls of 3–5, simple lanceolate and usually have serrated margins (entire in some species), 1–25 cm long, and can be either deciduous or evergreen depending on the species. The flowers are very decorative pendulous "eardrop" shape, borne in profusion throughout the summer and autumn, and all year in tropical species. They have four long, slender, sepals and four shorter, broader, petals; in many species the sepals are bright red and the petals purple (colours that attract the hummingbirds that pollinate them), but the colours can vary from white to dark red, purple-blue, and orange. A few have yellowish tones, and recent hybrids have added the color white in various combinations. The ovary is inferior and the fruit is a small (5–25 mm) dark reddish green, deep red, or deep purple, edible epigynous berry containing numerous very small seeds. Many people describe the fruit as having a subtle grape flavor spiced with black pepper.
