Scientific name: A clove is the flower bud of a tropical tree called clove tree (Eugenia Caryophyllata = Syzygium aromaticum). The word "caryophyllata" is Greek for "walnut leaves" and the name comes from the similarity with the leaves of this tree with the walnut tree. Its immature fruit was called in Spanish "clavo" (= nail) and similar names in other languages by the similarity it has with a nail.
The word comes from the Latin "clavus" meaning "nail" and was given its name from the resemblance of the flower buds of this plant with a rusty nail. In the Netherlands is known as "kruidnagel clove" which literally means " herbal nail" or "spice nail".
Habitat: It was originally a tree from the main islands of the Moluccas in Indonesia (The formerly known as the Spice Islands) in Southeast Asia. Specifically it appears that only grew larger islands (Ambon, Ternate, Buru and Banda).
At present, its cultivation has spread to Indonesia, Madagascar, Zanzibar, India and Sri Lanca. Indonesia has become the first country in the world. In 2005 this product will provide an income of 174,344,000 million dollars.
Characteristics of clove
The tree of cloves or clove tree is an evergreen tree of the myrtle family of up to 20 m high, but usually when it is cultivated., it does not usually exceed 10 m. Its stem is erect, and it has gray bark. Its leaves of up to 12 length, are pointed oval, oval-lanceolate or lanceolate, single, very aromatic, glossy green and leathery, like those of the sweet bay.
They are provided of numerous glands that confer it a sticky tact. Its flowers are arranged in inflorescences in the form of panicles at the end of young branches. They have four petals yellow roses and several pistils. The fruits (small and elongated dark red berries) sprout from the flowers. It breeds from sea level to 900 m in height.
How is clove obtained?
Most of the parts of the tree are aromatic, but flower buds are only collected before the flower opens. Interestingly, when fully developed, the flowers lose their fragrance, like its fruits, which are not aromatic.
Before the blooming of flowers, buds that already carry the future pink color of the petals are produced. The cloves are formed by the four petals of the corolla and the four pieces from the chalice, all of them still unopened. To harvest suitable cloves, they should be collected when the trees have a minimum of six years of age. A specimen of about 12 years old produces 2-9 kilos per year of dry clove. There are references that speak of specimens that produced more than 20 kilos per year of dry cloves. The trees tend to live about 100 years.
Cloves should be collected when the flower bud is not yet open. At first the buds are pink, but as they grow, they acquire a deep red hue. This is the right time to pick up the clove. Harvesting is done manually and then dried in the shade.
Work is carried out from September to February. For this, sticks to move the branches are used. This movement will make the cloves fall, usually on a mesh placed under the trees. Then they are dried. As they dry, they change to dark brown as we know them. Once dry they are collected. On some islands such as Zanzibar, it is the main task of the island, o such a degree that this island is also known as "Island of the clove."
