Nice gardenia picture with calyx and leaf|frane gardenia flower in the garden

Gardenia is a genus of 142 speciesof flowering plants in the coffee family, Rubiaceae, native to the tropical and subtropical regions of Africa, southern Asia, Australasia and Oceania.

The genus was named by Carl Linnaeus after Dr. Alexander Garden (1730-1791), a Scottish-born American naturalist.


They are evergreen shrubs and small trees growing to 1–15 metres (3.3–49 ft) tall. The leaves are opposite or in whorls of three or four, 5–50 centimetres (2.0–20 in) long and 3–25 centimetres (1.2–9.8 in) broad, dark green and glossy with a leathery texture. The flowers are solitary or in small clusters, white, or pale yellow, with a tubular-based corolla with 5-12 lobes (petals) from 5–12 centimetres (2.0–4.7 in) diameter. Flowering is from about mid-spring to mid-summer and many species are strongly scented.


Gardenia plants are prized for the strong sweet scent of their flowers, which can be very large in size in some species.

Gardenia jasminoides (syn. G. grandiflora, G. Florida) is cultivated as a house plant. This species can be difficult to grow because it originated in warm humid tropical areas. It demands high humidity to thrive and bright (not direct) light. It flourishes in acidic soils with good drainage and thrives on [68-74 F temperatures (20-23 C)] during the day and 60 F (15-16 C) in the evening. Potting soils developed especially for gardenias are available. G. jasminoides grows no larger than 18 inches in height and width when grown indoors. In climates where it can be grown outdoors, it can attain a height of 6 feet. If water touches the flowers, they will turn brown.


In China and Japan, Gardenia jasminoides is called Zhi zi  and Kuchinashi ; the bloom is used as a yellow dye, which is used for clothes and food. Its fruits are also used in traditional Chinese medicine for their clearing, calming, and cooling properties.

Camellia, the camellias, is a genus of flowering plants in the family Theaceae. They are found in eastern and southern Asia, from the Himalaya east to Japan and Indonesia. There are 100–250 described species, with some controversy over the exact number. The genus was named by Linnaeus after the Jesuit botanist Georg Joseph Kamel from Brno, who worked in the Philippines, though he never described a camellia. This genus is famous throughout East Asia; camellias are known as cháhuā  in Chinese, "flowering tea", an apt designation, as tsubaki  in Japanese, as dongbaek-kkot in Korean and as hoa trà or hoa chè in Vietnamese.

The most famous member – though often not recognized as a camellia – is certainly the tea plant (C. sinensis). Among the ornamental species, the Japanese Camellia (C. japonica) (which despite its name is also found in Korea and Eastern China) and C. sasanqua are perhaps the most widely known, though most camellias grown for their flowers are cultivars or hybrids.

These are world famous black rose picture in wall

 

Black roses (roses of black color) do not exist in nature as such, but nevertheless have been created in laboratories. Botanists have manipulated roses' genes through preliminary cross breeding, creating a hybrid black rose. They are often featured in fiction with many different meanings and titles such as black magic, barkarole, black beauty Tuscany superb, black Jade and baccara and death varieties of roses. The flowers commonly called black roses are actually a very dark shade of red, purple, or maroon. The color of a rose may be deepened by placing a dark rose in a vase of water mixed with black ink.

A rose is a woody perennial of the genus Rosa, within the family Rosaceae. There are over 100 species. They form a group of erect shrubs, and climbing or trailing plants, with stems that are often armed with sharp prickles. Flowers are large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwest Africa. Species, cultivars and hybrids are all widely grown for their beauty and fragrance. Rose plants range in size from compact, miniature roses, to climbers that can reach 7 meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses.


The leaves are borne alternately on the stem. In most species they are 5 to 15 centimetres (2.0 to 5.9 in) long, pinnate, with (3–) 5–9 (–13) leaflets and basal stipules; the leaflets usually have a serrated margin, and often a few small prickles on the underside of the stem. Most roses are deciduous but a few (particularly from South east Asia) are evergreen or nearly so.


The name rose comes from French, itself from Latin rosa, which was perhaps borrowed from Oscan, from Greek ρόδον rhodon (Aeolic βρόδον wrodon), related to Old Persian wrd-, Avestan varəda, Sogdian ward, Parthian wâr, Armenian vard.

Most favourite single red rose picture in the wallpaper photo

 

The flowers of most species have five petals, with the exception of Rosa sericea, which usually has only four. Each petal is divided into two distinct lobes and is usually white or pink, though in a few species yellow or red. Beneath the petals are five sepals (or in the case of some Rosa sericea, four). These may be long enough to be visible when viewed from above and appear as green points alternating with the rounded petals. There are multiple superior ovaries that develop into achenes.Roses are insect-pollinated in nature.


The aggregate fruit of the rose is a berry-like structure called a rose hip. Many of the domestic cultivars do not produce hips, as the flowers are so tightly petalled that they do not provide access for pollination. The hips of most species are red, but a few (e.g. Rosa pimpinellifolia) have dark purple to black hips. Each hip comprises an outer fleshy layer, the hypanthium, which contains 5–160 "seeds" (technically dry single-seeded fruits called achenes) embedded in a matrix of fine, but stiff, hairs. Rose hips of some species, especially the Dog Rose (Rosa canina) and Rugosa Rose (Rosa rugosa), are very rich in vitamin C, among the richest sources of any plant. The hips are eaten by fruit-eating birds such as thrushes and waxwings, which then disperse the seeds in their droppings. Some birds, particularly finches, also eat the seeds.
