Fruiting Orchid: Vanilla
Orchids have always been one of those enchanting flowers. Of the 35,000 or more species of this family, the vanilla orchid is the only orchid that produces “edible” fruit. Vanilla planifolia is the main species harvested, but other species with less vanillin content include Vanilla tahitiensis and Vanilla pompona. Vanilla planifolia orchid is commonly found in the food and cosmetic industry.
Vanilla grows as a climbing vine, usually in existing trees. It’s native to Mexico, in the states of Vera Cruz and Oaxaca. But it is now cultivated around the world, with Madagascar being the largest producer of vanilla.
Vanilla flowers bloom only once and only for a few hours. And once it’s been pollinated, the vanilla bean can take from six months to one year to mature.
There are many ways to harvest the vanilla beans, it is a very labor intensive process. But it’s important that the beans are completely dried and cured. During this process, the sweet and spicy aroma of Vanilla comes out. Dried and cured vanilla beans can be kept for 10 years or more.
If you are lucky enough to live in a hot and humid location, propagation of vanilla plants may be possible. A section of the plant (cutting) is removed from the vine with six or more leaf nodes, along with a root opposite each leaf. The two lower leaves are removed, and this area is buried in loose soil at the base of a support. The remaining upper roots will cling to the support.
This neat photo is from Huahua Farm in Hawaii. The Vanilla plant looks so healthy with creamy greenish-yellow flowers. If anyone is interested, in May Huahua Farm will be offering two vanilla beans for sale at $8.50, includes postage.
