Vanilla is an orchid that flowers abundantly and fruits rarely. Between the two stands a manual gesture, repeated flower after flower, morning after morning, throughout the flowering season.
How long does the flower stay receptive
The vanilla flower opens at first light and stays receptive for a few hours, six to twelve depending on the heat. Past that, the window is closed. Flowering spreads over several weeks and each vine opens a few flowers a day, which calls for a daily pass through the plots. A flower missed is a pod lost.
A simple reference
One flower, one morning, one gesture. The rhythm of pollination is the rhythm of daybreak.
Why is vanilla pollinated by hand
In vanilla, the male and female organs occupy the same central column, a few millimetres apart. A fine membrane, the rostellum, separates them. This partition protects the genetic integrity of the plant by holding the pollen away from the stigma.
In its native habitat, the flower sometimes finds an insect able to cross this partition. Such spontaneous fertilisations remain rare. Wild vanilla accounts for a minute share of world production. The exact identity of these visitors still occupies botanists. The hand took over because it brings the regularity that cultivation requires.
A gesture born in 1841
The gesture carries the name of Edmond Albius. A child held in slavery on the island of Réunion, he was about twelve when, around 1841, he found the way to cross the rostellum: a fine sliver of bamboo to lift the membrane, then a press of the thumb bringing the anther against the stigma. A few seconds are enough.
His method spread quickly and opened vanilla cultivation far beyond its native range. Freed in 1848 with the abolition of slavery in the French colonies, Edmond Albius died in 1880. His gesture remains that of nearly all the vanilla in the world, unchanged since.
The letters that tell the scene keep an uncertain memory of the year. The path of Edmond Albius is set out in his article.
The morning of the marieuses
The round begins at four in the morning. It ends towards ten, when the heat becomes too strong for the flower as for the hand. Everything is decided between those two hours.
The tool fits in the palm, an orange-tree thorn cut fine, rigid enough to lift the rostellum without harming the column. Its nature has not changed since Albius's sliver of bamboo, only its material.
The women who make this gesture have a name. Les marieuses, the ones who marry the flowers. A morning can hold up to 1,500 flowers for each of them.
How to know whether the flower has taken
The answer comes two to four days later. It reads on the vine.
The flower stalk curves clearly towards the ground. The base of the flower stays a deep green, firms up, begins to swell into the future pod. The faded flower holds on: the petals brown and dry while staying firmly attached to the outside of the young pod.
Without fertilisation, the flower follows another path. From the afternoon the petals close again and wilt. Within twenty-four hours it yellows, the plant having stopped feeding it. It browns over the following twenty-four to forty-eight hours, then detaches on its own two to three days after opening.
The hand that decides the pod
Pollination already engages the future quality. The number of flowers fertilised on a single vine determines the load the plant will have to carry. A reasonably loaded vine gives pods richer in oils, more supple and more regular. An overloaded vine scatters its resources.
This adjustment is made by eye, vine by vine, according to the vigour of the plant and the season. It is a grower's judgement, made on a morning of flowering for a substance that no one will taste for many months.
From the gesture to the pod
A flower fertilised in the morning gives a green pod that grows for a few weeks, then ripens on the vine for eight to nine months. Then comes the harvest, then the preparation that fixes the aromas, then the long months of maturation during which the aromatic spectrum gains its depth and its complexity.
Between that morning of flowering and the pod that joins a cream or a ganache, close to eighteen months go by. Pollination is the first gesture, the one on which all the others depend.
This gesture is also what allowed vanilla to leave Mexico. Its journey to the SAVA is told in how vanilla reached Madagascar. The species the island already carried are described in the wild vanillas of Madagascar.

Frequently asked questions
Why is vanilla pollinated by hand?
In vanilla, the male and female organs occupy the same central column, separated by a fine membrane called the rostellum. This partition keeps the pollen away from the stigma. Spontaneous fertilisations remain rare, so the manual gesture brings the regularity that cultivation requires.
How long does the flower stay receptive?
The vanilla flower opens at first light and stays receptive for six to twelve hours depending on the heat. Without fertilisation it drops from the vine the same day. Flowering spreads over several weeks, which requires a daily pass through the plots.
