While you're baking cookies and cakes this holiday season, you'll probably have vanilla extract in your hands more than once. If you're using pure, unadulterated vanilla extract (as opposed to its copy-cat imitation vanilla extract), you just might notice the steep price, as well. If you're holding a bottle of pure vanilla extract at a cheap price, it's probably adulterated (not as "pure" as it should be).

So why are vanilla beans so expensive?

It may surprise you to learn that vanilla bean pods come from an orchid (which already sounds expensive). In fact, the vanilla orchid (Vanilla planifolia) is the only orchid that produces an edible fruit. It was originally discovered climbing among the trees in Mexico and was later introduced to other warm tropical and subtropical regions of the world.

It's only one of about 100 climbing and terrestrial (land) orchids and can climb anywhere from ten to eighty feet into trees or shrubs. Vanilla orchid's natural pollinator is a Melipona bee species that is only found in Mexico. So, for many years this was the single resource for vanilla beans.

Today, vanilla is grown commercially in Madagascar, Caribbean, Mexico, Comoro Islands, Indonesia, Hawaii, and Tahiti. The cultivation of vanilla is extremely labor-intensive. The plants themselves don't even start producing vanilla beans until after three years. When they finally do bloom, the flowers only stay open for one day and have to be carefully pollinated within 12 hours of blooming.

To ensure pollination and the best vanilla bean flavor, each flower on every orchid is hand-pollinated. This is especially true for plants grown in areas other than Mexico where there would at least be the Melipona bees to help out.

This is harder than it sounds considering the flowers are opening every day at different times for several weeks. It takes nine full months for the seed pods to mature enough to harvest and every pod matures at a different rate. Which means, like the tedious flower pollination, workers are harvesting daily for three to four weeks at a time. Following the harvest, the seed pod curing process takes another three months. There's simply no rushing the production of pure vanilla extract, which is why this liquid spice remains so expensive.

Growing Your Own Vanilla Bean Plant

Vanilla orchids are evergreen plants with 6 " inch, yellow-green, fleshy foliage. Vanilla likes a neutral soil pH (6.6 - 7.5). Although you may not see a bloom on a cutting for a couple of years their blossoms show up in mid-spring to late summer -- and only for one day. The tubular flowers are white, yellow or green and about 5" inches across. If the flowers are successfully pollinated (which would have to be done by the gardener), 6"-10" long seed pods will follow about nine months later.

Vanilla orchids prefer high humidity and should be grown in an area where nighttime temperatures don't drop below 55 degrees, which makes gardens in USDA zones 10-11 their best bet. Bright light & filtered shade is preferred and the potting medium should be well-draining and humus-rich. Yes, you could come up with your own blend, but it's easier to purchase a proper soil mix specific to orchids.

Keep the soil evenly moist at all times taking care not to over-water at the same time. This orchid may not like its feet to dry out between waterings, but it doesn't want rotten roots either. During the spring and summer, lightly fertilize your vanilla bean plant every two weeks with an orchid fertilizer. Offer the vines some type of support for climbing and clinging such as a wooden trellis.

Vanilla bean plants aren't especially hard to grow but if your outdoor climate isn't ideal they're well-suited to the greenhouse, as well as indoors among other houseplants.

esmithorchids writes: I am an avid Orchid grower and I must say that growing a Vanilla Orchid has been one of my biggest challenges. I bought 5 cutting online and only 4 survives the trip. I have been nursing the other 4 for three years through the thick and thin but have not yet seen a bloom. They are of a large enough size, from what I can tell online, to bloom any day now so wish me luck!
