Scientific Names



Hibiscus, or rosemallow, is a large genus of about 200–220 species of flowering plants native to warm, temperate, subtropical and tropical regions throughout the world. The genus includes both annual and perennial herbaceous plants, and woody shrubs and small trees.

The leaves are alternate, simple, ovate to lanceolate, often with a toothed or lobed margin. The flowers are large, conspicuous, trumpet-shaped, with five or more petals, ranging from white to pink, red, purple or yellow, and from 4-15 cm broad. The fruit is a dry five-lobed capsule, containing several seeds in each lobe, which are released when the capsule splits open at maturity.

Species

In temperate zones, probably the most commonly grown ornamental species is Hibiscus syriacus, the common garden Hibiscus, also known in some areas as the "Rose of Althea" or "Rose of Sharon" (but not to be confused with the unrelated Hypericum calycinum, also called "Rose of Sharon"). In tropical and subtropical areas, the Chinese hibiscus (H. rosa-sinensis), with its many showy hybrids, is the most popular hibiscus.

About 200-220 species are known, including:

Care

Hibiscus flowers need to be taken care of in warm temperatures. They bloom best with temperatures ranging from 60 to 90 degrees. The hibiscus needs to be watered carefully. Make sure you do not overflood the roots. Keep a steady flow of water for the plant in warm weather. In colder weather, only water the plant if it looks dry. Hibiscus needs to be fed plant food. Try to keep all insects and pests away so the flower does not get ruined. If you are potting your flower, make sure the pot has plenty of drainage.

Propagation

Mainly by rooting cuttings.

Pests and diseases

Whitefly, aphids, scales, etc.

Uses

A white Hibiscus arnottianus in Hawaii.
A red Hibiscus of Kerala
(Hibiscus rosa-sinensis).

Many species are grown for their showy flowers or used as landscape shrubs. Hibiscus is also a primary ingredient in many herbal teas.

One species of Hibiscus, known as Kenaf (Hibiscus cannabinus), is extensively used in paper making. Another, roselle (Hibiscus sabdariffa) is used as a vegetable and to make herbal teas and jams (especially in the Caribbean).

In Mexico, the drink is known as Jamaican water or agua de Jamaica and is quite popular for its color, tanginess and mild flavor; once sugar is added, it tastes somewhat like cranberry juice. Dieters or persons with kidney problems often take it without adding sugar for its beneficial properties and as a natural diuretic. It is made by boiling the dehydrated flowers in water; once it is boiled, it is allowed to cool and drunk with ice.[1]

In Egypt and Sudan, roselle petals are used to make a tea named after the plant karkade.

Hibiscus species are used as food plants by the larvae of some Lepidoptera species including Chionodes hibiscella, Hypercompe hambletoni, the Nutmeg moth, and the Turnip Moth.

The Hibiscus is used as an offering to Goddess Kali and Lord Ganesha in Hindu worship. The Gumamela or Hibiscus rosa sinensis linn flower has antifungal, emmenagogue, emollient and refrigerant effect.[240]

The bark of the hibiscus contains strong fibers. They can be obtained by letting the stripped bark sit in the sea in order to let the organic material rot away. In Polynesia these fibers (fau, pūrau) are used for making grass skirts. They have also been known to be used to make wigs.

Hibiscus, especially white hibiscus, is considered to have medicinal properties in the Indian traditional system of medicine, Ayurveda. Roots make various concoctions believed to cure various ailments.

The natives of southern India use the Red hibiscus (Hibiscus rosa-sinensis) for hair care purposes. The red flower and leaves, extracts of which can be applied on hair to tackle hair-fall and dandruff on the scalp. It is used to make hair-protective oils. A simple application involves soaking the leaves and flowers in water and using a wet grinder to make a thick paste, and used as a natural shampoo.

Dried hibiscus is edible, and is often a delicacy in Mexico.
