Wild vanilla may face a pollination problem in the future – one that will ultimately affect the food industry too.
Vanilla works wonderfully in ice cream and other sweet treats, but the future of that scoop of vanilla is uncertain. The plant itself is faring less well. Vanilla faces increasing difficulties under rising global temperatures, partly because the pollinators of wild vanilla will increasingly be found in different areas from the plant. This is the conclusion of research by a predominantly Belgian team of botanists (Frontiers in Plant Science, 3 July). Although some vanilla species may actually expand their range under future climate scenarios, the habitat of their pollinators is set to shrink substantially. As a result, the overlap between the ranges of pollinator and pollinated plant is contracting.
For the food industry, this is not an immediate problem, since growers pollinate vanilla by hand. Wild vanilla does, however, represent a valuable source of variants that are resistant to diseases or drought, for example. Growers readily draw on the genetic diversity of wild vanilla species when their crops run into trouble.
In sweet desserts and other vanilla-enriched treats, it is usually Vanilla planifolia that provides the flavour. This is precisely the species facing an uncertain future in the wild, because as far as is known, only the orchid bee Euglossa dilemma pollinates it. The overlap between their ranges is projected to decrease by around 60 to 64 per cent under various climate scenarios.
Small pod
The genus name Vanilla is derived from the Spanish word vainilla, meaning ‘small pod’. The species epithet planifolia also refers to the plant’s appearance; it is Latin for ‘flat leaves’. The species is also known as V. fragans. Fragans means ‘sweet-smelling’ and was in itself an apt name, but the American botanist Oakes Ames did not coin it until 1924, whereas the English botanist Henry Andrews had already described the species as V. planifolia back in 1808. V. planifolia therefore takes priority. The plant itself could perhaps do with some priority when it comes to protection as well.
