Vanilla

What does Vanilla look like?

Vanilla planifolia is a climbing orchid with long, fleshy green stems that can reach up to 30 meters. Its leaves are glossy, bright green, and shaped like narrow ovals, growing up to 25 cm long. The flowers are greenish-yellow, about 5 cm wide, and appear in clusters. Each flower lasts only a day and has a faint scent. After pollination, the plant produces slender pods, often called beans, which are 15–23 cm long and look a bit like small bananas.

Where does Vanilla come from?

This orchid is native to the humid forests stretching from southern Mexico through Central America to northern Brazil. It was first described scientifically in 1808, though it was known and used long before then. The plant spread from its native forests as people began to cultivate it for its valuable pods, which are now grown in tropical regions worldwide. Much of the world’s vanilla comes from plants descended from a single introduction to the Indian Ocean islands in the 1800s. Wild populations are now rare and declining due to habitat loss.

When and how Vanilla blooms

Vanilla planifolia blooms once a year, with flowers opening in spring. In the wild, pollination is rare and depends on certain bees, but on farms, flowers are pollinated by hand. The plant needs a warm, humid climate, well-drained soil, and some shade. It is usually grown from cuttings. After pollination, pods take eight to nine months to mature. Once ripe, they are harvested and cured through fermentation and drying to develop the familiar vanilla flavour.

How Vanilla is used

The main use of Vanilla planifolia is for its pods, which are the source of natural vanilla flavouring used in food and perfume. The pods are also valued for their aroma and are sometimes used in traditional medicine. Because natural pollinators are scarce, most cultivated vanilla is pollinated by hand. The sap can cause skin irritation, so care is needed during harvest.

Kinds of Vanilla

There are only a few named cultivars of Vanilla planifolia, with 'Handa' being the only patented one as of 2023. Most commercial vanilla comes from 'Mansa' types. Two variegated forms are grown as ornamentals. Almost all vanilla grown around the Indian Ocean descends from a single introduction, which has led to low genetic diversity.

What Vanilla means

Vanilla planifolia is the world’s main source of natural vanilla, a flavour prized in cooking and fragrance. Its cultivation was central to rural economies in Mexico and later spread globally. The species is now listed as Endangered due to habitat loss and declining wild populations. The plant’s sap can cause dermatitis in workers. Vanilla’s unique pollination and seed dispersal by animals and bees are rare among orchids.
