The Roselle ( Hibiscus sabdariffa ), also Sabdariff Marshmallow , Sudan Marshmallow , African mallow or Karkade called, is a plant from the family of mallow (Malvaceae). It is native to southeast Asia .
description
The Roselle grows as an annual herbaceous plant and reaches a height of 2 to rarely 3 meters. Most of the vegetative parts of the plant are softly hairy. The upright stem is purple in color. The leaves are stalked 2 to 8 cm long. There are two different forms of leaf blades: egg-shaped and finger-shaped three-lobed with narrow lobes. The thread-like stipules are about 1 cm long.
The flowers are solitary in the leaf axils. The large (diameter 6 to 7 cm) flowers are hermaphroditic, radial symmetry and five-fold. The secondary calyx has eight to twelve red, fused lobes at their base with a size of 5 to 15 × 2 to 3 mm. The five purple, fleshy sepals are jug-shaped over about a third of their length. The five petals are yellow and dark red at the base. In the subfamily Malvoideae , the stamens of the many stamens have grown together to form a tube surrounding the pistil , the so-called columna .
The five-fold capsule fruit is egg-shaped to spherical with a diameter of about 1.5 cm.
The number of chromosomes is 2n = 18, 36 or 72.
use
The calyx, which becomes fleshy when the seeds are ripe and changes its color to a bright red, is characterized by its good taste and pleasant acidity. It is therefore used to make hibiscus tea, desserts, lemonades, jams and liqueurs. In the dried form it is used in Sudan and Egypt as a tea, which is known as Karkadeh . In Senegal and Mali, tea is served cold with a lot of sugar. In Senegal, Cabo Verde and Burkina Faso the drink is known under the name "Bissap", in Mali under "Dableni" and in Cameroon under "Folleré" and is a national drink in both countries. In Meso and South America, hibiscus tea is known as "agua de flor de Jamaica" or "agua de Jamaica" and the plant is also known as "flor de Jamaica" or "rosa de Jamaica". In Trinidad and Tobago , the calyxes are boiled down with sugar, cloves and cinnamon and the resulting syrup is used as the basis for soft drinks. The plant is called “sorrel” there and is also processed industrially, so bottled Sorrel soft drinks and a Sorrel beer mix from Carib Brewery are available in supermarkets . The leaves can also be cooked like vegetables.
Similar to the East Indian hemp marshmallow , which is very similar to the roselle, Hibiscus sabdariffa also provides fibers that can be processed like jute . Residues that arise after fiber production are used to manufacture paper. Roselle is now grown in many developing countries because it allows independence from jute imports.
