It's cultivated throughout the tropics with Madagascar and Indonesia being major producers.
There are about 150 varieties and many of them are leafless.
The seed pods are harvested before they are fully ripe - at that time they have neither flavour nor fragrance.

The long and complicated curing process and the need of manual pollination are some of the reasons why vanilla is one of the most expensive spices.
