Hibiscus rosa-sinensis

provided by wikipedia EN

Hibiscus rosa-sinensis, known colloquially as Chinese hibiscus,[2] China rose,[2] Hawaiian hibiscus,[2] rose mallow[3] and shoeblackplant,[4] is a species of tropical hibiscus, a flowering plant in the Hibisceae tribe of the family Malvaceae. It is widely cultivated in tropical and subtropical regions, but is not known in the wild, so that its native distribution is uncertain.[5] An origin in some part of tropical Asia is likely.[2]

A shrub from the family Malvaceae that is native to East Asia, it is widely grown as an ornamental plant in the tropics and subtropics.

Nomenclature

Hibiscus rosa-sinensis was named in 1753 by Carl Linnaeus in his Species Plantarum.[6] The Latin term rosa-sinensis literally means "rose of China", though it is not closely related to the true roses.[7]

Description

Hibiscus rosa-sinensis is a bushy, evergreen shrub or small tree growing 2.5–5 m (8–16 ft) tall and 1.5–3 m (5–10 ft) wide, with glossy leaves and solitary, brilliant red flowers in summer and autumn. The 5-petaled flowers are 10 cm (4 in) in diameter, with prominent orange-tipped red anthers.[8]

The flowers are large, conspicuous, trumpet-shaped, with five petals and their colors can be white to pink, red, orange, peach, and yellow or purple that are 4–18 cm broad. The flowers from various cultivars and hybrids can be either a single flower or a double flower. Flower color in certain species, such as H. mutabilis and H. tiliaceus, changes with age This flower has a crown that consists of 15 - 20 leaves which are alternate and ovate.

At the bottom of every hibiscus bud is the calyx which is green in color. The pointed ends of the calyx are the sepals. When the hibiscus begins to bloom, the petals begin to grow which contains multiple petals and multiple colors. The ovary and other female parts of the flower lie in the main structure of the hibiscus, the pistil, which is long and tubular. The hibiscus has both male and female parts on the same flower. The five hairy red spots on the top of the flower is the stigma (female part) of the flower. The stigma is located at the end of the style branch. At the top of the pistil is known as the stigma, where pollen is collected, and in the middle is the style, which is the section that the pollen travels down to the ovary. The ovary lies at the bottom of the blossom and the hibiscus has only one ovary which is superior.

The male part (stamen) of the flower consists of stem-like filaments and each filament ends with the pollen-producing anther. The anthers, which release the pollen, sits on the filament and these two organs make up the stamen, the male part of the flower. Together, these organs make up the male part of the flower known as the stamen. The hibiscus has hundreds of stamens. Overall, the hibiscus is a dicot, solitary (axillary), complete, perfect, has a superior ovary, regular symmetry, and axile placentation. It has 5 carpels, 5 locules, 5 sepals, and the amount of stamens may vary.

The root is a branched tap root. The stem is aerial, erect, green, cylindrical and branched. The leaf is simple, with alternate phyllotaxy and is petiolate. The leaf shape is ovate, the tip is acute and margin is serrated. Venation is unicostate reticulate. (Venation is branched or divergent.) Free lateral stipules are present.

Floral characters

The flower is

Epicalyx are present, valvate aestivation, free. Calyx are gamosepalous, valvate, sepaloid. Corolla are polypetalous, twisted, petaloid. Indefinite stamens, monoadelphous. Gyanoecium pentacarpellary, ovary superior, placentation axile, syncarpous.

It can bloom all year round.

Ecology

Despite its size and red hues, which are attractive to nectarivore birds, it is not visited regularly by hummingbirds when grown in the Neotropics. Generalist species, like the sapphire-spangled emerald, Amazilia lactea, or long-billed species, like the stripe-breasted starthroat, Heliomaster squamosus, are occasionally seen to visit it, however.[9] In the subtropical and temperate Americas, hummingbirds are regularly attracted to it.[10]

The endangered Papilio homerus butterfly, the largest in the western hemisphere, is known to feed on the nectar of the Hibiscus.[11]

Genetics

Hibiscus rosa-sinensis is one of many plant species with a genetic characteristic known as polyploidy, in which there are more than two complete sets of chromosomes, unlike most other species.[12] A side effect of polyploidy is a condition where the phenotype of the offspring may be quite different from the parent, or indeed any ancestor, essentially allowing possibly random expression of all (or any) of the characteristics of all the generations that have gone before. Because of this characteristic, H. rosa-sinensis has become popular with hobbyists who cross and recross varieties, creating new named varieties and holding competitions to exhibit and judge the many resulting new seedlings and often strikingly unique flowers.

Uses

The flowers of Hibiscus rosa-sinensis are edible and are used in salads in the Pacific Islands. The flower is additionally used in hair care as a preparation. It is also used to shine shoes in certain parts of India. It can also be used as a pH indicator. When used, the flower turns acidic solutions to a dark pink or magenta color and basic solutions to green. It is also used for the worship of Devi, and the red variety is especially prominent, having an important part in tantra. In the Bengal area of eastern India, the red variety of this flower is used to worship Kali. In Indonesia, these flowers are called "kembang sepatu", which literally means "shoe flower". In several countries the flowers are dried to use in a beverage, usually tea.

Hibiscus rosa-sinensis is considered to have a number of medical uses in Chinese herbology.[13] Traditional uses in China have been to make a black shoe-polish from its crushed flower petals, or to make a woman's black hair dye.[14] The flowers are also used in China to color various intoxicating liquors.[14] The plant may have some potential in cosmetic skin care; for example, an extract from the flowers of Hibiscus rosa-sinensis has been shown to function as an anti-solar agent by absorbing ultraviolet radiation.[15]

Cultivation

It is widely grown as an ornamental plant throughout the tropics and subtropics. As it does not tolerate temperatures below 10 °C (50 °F), in temperate regions it is best grown under glass. However, plants in containers may be placed outside during the summer months or moved into shelter during the winter months.[8][16]

Numerous varieties, cultivars, and hybrids are available, with flower colors ranging from white through yellow and orange to scarlet and shades of pink, with both single and double sets of petals. The cultivar 'Cooperi' has gained the Royal Horticultural Society's Award of Garden Merit.[3][17]

National symbol

Hibiscus rosa-sinensis is the national flower of Malaysia, called Bunga Raya in Malay. Introduced into the Malay Peninsula in the 12th century, it was nominated as the national flower in the year 1958 by the Ministry of Agriculture amongst a few other flowers, namely ylang ylang, jasmine, lotus, rose, magnolia, and medlar. On 28 July 1960, it was declared by the government of Malaysia that Hibiscus rosa-sinensis would be the national flower.

The word bunga in Malay means "flower", while raya in Malay means "celebratory" or "grand". The Hibiscus rosa-sinensis is literally known as the "celebratory flower" in Malay. The red of the petals symbolizes the courage, life, and rapid growth of the Malaysian, and the five petals represent the five Rukun Negara of Malaysia. The flower can be found imprinted on the notes and coins of the Malaysian ringgit.

In Haiti, the flower has the character of an unofficial national flower, becoming used for a time, as a symbol of the country brand for the promotion of tourism, where it is known in Haitian Creole language as choeblack or rose kayenn.[18][19] In addition, it is the symbol of the party Fusion of Haitian Social Democrats.

Cultural references

  • In India, the flower is also used for pray of goddess Durga & kali.
  • In March 1987 DPR Korea issued a postage stamp depicting Hibiscus rosa-sinensis.
  • On 7 October 2012, Sri Lanka too, issued a stamp set of four and one of it carried a Hibiscus rosa-sinensis flower.

Cultivars with flowers of many colours are used as ornamental plants. Some are double or have differently shaped petals.
