The Complete Guide To Floral Scents
Flower Scent Basics
Floral scent or flower scent is composed of all the volatile organic compounds (VOCs), or aroma compounds, emitted by floral tissue (e.g. flower petals). Floral scent is also referred to as aroma, fragrance, floral odour or perfume.
The alluring chemical cocktails we smell in the air are a mixture of volatile organic compounds (VOCs) and low-molecular-weight lipophilic (oil- and fat-soluble) liquids. VOCs include alcohols, aldehydes, ketones, esters, and other miscellaneous hydrocarbons. More than 1,700 VOCs have been identified from 90 different plant families.
For an individual flower, the cocktail can comprise over 100 different compounds. For example, the intoxicating flowers of the Lonicera japonica, a species of honeysuckle, have over 150 volatile compounds.
In nature because flowers cannot move about in order to spread their seeds, plants and flowers use scent to attract birds and insects to them in order to pollinate. As each bird, bee or insect lands on a flower it picks up pollen and, when it lands on the next flower, it leaves some behind while taking away new pollen.
A plant’s production of attractants is an energy-intensive process. To balance the use of resources, some plants only produce scent chemicals during specific times of day. Jasmine only produces its scent during the evening and nighttime hours when its own dedicated pollinators (moths) are active. This is why the fragrance carried by a summer breeze changes as the afternoon moves from evening to night.
Whether it’s attracting insects to a pollen-rich stamen or producing seed-laden fruit for birds to eat, plants and flowers rely on the rest of nature to help them procreate. For the majority of flowers and plants, it is their scent that helps them to achieve this and every fragrance is attuned to the right creature that the flower requires.
Scent is also used as a deterrent to stop herbivores from eating the plant. By producing a foul or bitter scent, the flower can put off potential predators and warn creatures that they don’t taste very nice. This has no effect on insects however as they are attracted to less appealing aromas.
How we smell floral aromas
Our ability to enjoy scents relies on our own personal chemoreception sensors: our noses. The nose contains olfactory receptors that can bind to the odorant molecules entering the nose. Binding changes the overall shape of the molecule, setting off a series of reactions that informs your brain as to what you are smelling. Over 390 olfactory receptors have been identified, which can detect thousands of different odorant chemicals, many at concentrations as low as 1 part per 30 billion.
Floral scents are one of the most popular smells that people like to enjoy, and it has been discovered that certain fragrances can have an effect on our emotions and wellbeing.
