Botanical Name : Vanilla planiforlia
Species: Vanilla planifolia
Synonyms: Vanilla planifolia Jacks, Notylia planifolia
Common name: Vanilla
Habitat:Vanilla planiforlia is native to Mexico and Central America. It grows in the tropical forests.
Vanilla planifolia is a tropical vine, which can reach a length of over 30 m. It has thick, fleshy stems and greenish flowers that open early in the morning and are pollinated by bees. The flowers have only a slight scent, with no element of the vanilla flavour or aroma. Once pollinated, the ovaries swell and develop into fruits called ‘pods’ similar to long, thin runner beans over a period of four weeks. The pods contain thousands of tiny black seeds.

Chris Ryan of Kew’s Tropical Nursery has found that propagation of this orchid is relatively straightforward and is usually done from stem cuttings.
A piece of stem is taken, with a minimum of three sets of leaves. The cutting is placed on sphagnum moss and kept damp in a warm and humid environment until new growth starts from one of the nodes. The cuttings are then planted into hanging baskets, using a compost mix made of three parts bark chips, two parts pumice and one part charcoal. The compost is watered only when it dries out, but the aerial roots are misted once a day.
The plants are kept in a warm zone of the nursery, with a minimum winter temperature of 18?C, and shaded when necessary. When the plants become large they require some support due to their climbing habit. Flowering can be induced by tip-pruning established plants, which promotes flowering on lateral shoots.
Edible Uses:The tiny seeds, whole fruit, powder or fruit extract of vanilla are used as flavouring agents in food, particularly in confectionery and sweet foods, sometimes to reduce the amount of sugar necessary to sweeten food.
Vanilla is used medicinally as an aphrodisiac, as a stimulant, and to relieve fevers and gastric complaints, although there is no scientific evidence for its effectiveness in these cases. In the 16th and 17th centuries vanilla was believed to have various medicinal properties and was used as a stomach herb, a stimulant and aphrodisiac and an antidote to poisons. It was first included in European pharmacopoeias in the 18th century and was listed in the British and American ones for many years. It acts on the nervous system and used to be used to treat hysteria and high fevers.
Research has shown that vanillin, the main flavour molecule in vanilla, does have antimicrobial and antioxidant activities.
Vanilla is among the most important ingredients in perfumery.
Vanilla: Essence and aroma
The mature, unripe fruits have no flavour when they are harvested. The aroma and flavour of vanilla are released when the fruit is dried and cured by steaming and fermentation. The finest quality vanilla pods turn dark brown and accumulate a frosting of glucose and vanillin on the surface during fermentation.
Vanillin was first synthesised in 1874 from a compound extracted from pine bark, and then in 1891 from a different compound extracted from cloves, and is widely used as a synthetic substitute for natural vanilla. The ‘vanilla essence‘ commonly used today is synthesised from wood pulp as a by-product of paper-making and from coal-tar (toluene). However, the characteristic aroma and flavour of natural vanilla comprises a cocktail of over 200 different molecules.
Known Hazards: Vanilla may cause allergic responses when applied topically or taken internally. ‘Vanillism’ is a condition sometimes experienced by workers handling vanilla, the symptoms of which are headache, dermatitis and insomnia.
