The vanilla orchid is beautiful, but do you know how to grow vanilla beans from that lovely plant? We delve into this complex topic!One of the most beloved flavors in the world is vanilla. Vanilla extract is essential for baking, and it’s a lovely flavor for most confections. This leaves a lot of gardeners wondering how to grow vanilla at home. Vanilla bean plants are lovely climbing orchids that host vanilla beans with patience.
But growing vanilla bean plants isn’t as simple as planting seeds and watching them take off. A vanilla orchid has specific needs, based on the native habitat of vanilla orchids altogether. You may already have some idea of what growing orchids is like, but don’t let that discourage you!
It’s possible to grow a vanilla bean plant in a controlled environment. With so many different types, you can have vanilla flavoring of many kinds. Your own vanilla seed pods will taste that much better when you’ve done the planning and work of caring for a vanilla bean orchid. Let’s cover caring for vanilla plants, and the different varieties out there. You’ll be on your way to growing your own vanilla pods in no time. This piece covers the two most popular cultivars of vanilla plants: Vanilla planifolia and Vanilla tahitensis. These are commonly referred to as Vanilla, vanilla orchid, flat-leaf vanilla, or West Indian vanilla. Vanilla tahitensis originates from southern North America where Aztec peoples hybridized two varieties into one. Vanilla planifolia is native to Guatemala, Mexico, and Belize. Both were transferred to Europe via Spanish conquistadors in the years 1300-1500. These are vines that use trees for support. They grow in a tropical climate under rainforest lower canopies. The vines zig-zag and have elliptic leaves. After a few years of vanilla vine growth, a greenish, yellow, or white flower forms. The flower lasts only one day. In this small window, self-fertile flowers pollinate. If no pollination occurs, the flowers drop.
As the climbing vine matures a few years and pollination is successful, the fruit begins to form. They first resemble small 6 to 9-inch bananas that take about 6 months to mature. Aged pods are harvested and cured for extraction. Usually, the entire pod is macerated and distilled in alcohol for flavoring. Some scrape the inside of the pod and use real vanilla to flavor all kinds of culinary confections. Most of the plants used for growing vanilla extract come from Madagascar, Tahiti, and Mexico. It can only be cultivated in the wild at 10-20 degrees north and south of the equator. In captivity, it is necessary to hand pollinate.
Here are a few of the varieties commonly cultivated by curious gardeners who are up for the challenge.
West Indian Vanilla (Vanilla pompona): a lovely plant with large glossy green leaves and long thin stems up to 5 meters long. Native to Mexico, and South Tropical America. Bunches of fragrant flowers open in succession and produce long pods.
Flat-leaved vanilla (Vanilla planifolia): one of the largest plants, this cultivar grows up to 30 meters. It prefers a swamp habitat or tropical environment.
Tahitian Vanilla (Vanilla tahitensis): native to Tahiti, this vanilla bean plant has yellowish-green flowers that produce broader, more squat pods than West Indian. This is one of the most common vanilla bean plant cultivars, and the vanilla extract has a flavor distinct from other varieties.
Leafless Vanilla (Vanilla aphylla): native to Southeast Asia, this vanilla bean plant has clusters of three to four flowers that bloom in spring and summer. Unlike other cultivars, leafless vanilla has no foliage. Flowers grow directly from internodes situated evenly on vines.
Mexican Vanilla (Vanilla mexicana): this vanilla bean is native to Central Florida, Mexico, and areas of Central and South America. One of the most common varieties, it grows squat and short at less than 2 feet in length.
Unless you live in a region where tropical conditions exist year-round, you’ll want to have a controlled environment for your vanilla plant. If you live in Southern Florida, the base of a tree in an area where there is bright filtered shade in the afternoon might work. In all other regions, plant vanilla plants in small pots with an orchid potting mix. Make sure your orchid has a pole to climb or some kind of support system for upward mobility. The container and potting medium need adequate drainage, as orchids of this kind do not like to be waterlogged. Use a sanitized cutting implement, and remove ⅓ of the bottom roots. Then, plant the rest of the plant and add your stake, pole, or whatever you will use to train your vanilla plants.
