Vanilla planifolia
The majority of the world's vanilla is the vanilla planifolia species, more commonly known as Bourbon vanilla or Madagascar vanilla. It is produced in Madagascar and the neighboring islands of the southwestern Indian Ocean and in Indonesia. It prefers hot, wet, tropical climates.
Vanilla planifolia is currently the most popular and widely consumed vanilla on the international market. It produces greenish-yellow flowers last only a day, and must be pollinated manually. In the wild, there is less than 1% chance that these flowers will be pollinated, so in order to receive a steady flow of fruit, the flowers must be hand pollinated when grown on farms.
