The Scents and Smells of Orchids

Humour Your Nose with
The Good Scent (Perfume and Fragrance) and
The Bad Smell (Stink and Stench)

Being eye candies aside, scented orchids impart a bonus sensory dimension to the appreciation of the largest flowering plant family, the diversity of which is also commandingly reflected in the enormous variety of Scents and Smells of orchids, ranging from the ethereally aromatic and intimately sweet-smelling to the needlessly displeasing and even dauntingly putrescent, if not demoralizingly nauseating.

In spite of the subjectivity of sensory perceptions and the diversity of orchid fragrances, there is a high degree of consensus in how orchids smell to the human nose. In addition, there are sociocultural differences in the degree to which the presence and quality of fragrance are considered desirable, admirable or even obligatory in orchids. Such differences can be quite pronounced in certain genera, especially Oriental Cymbidiums, many of which are fragrant orchid competition winners, and are highly prized for their elegant and diffusive aromas, often described as a sophisticated blend of jasmine, lily-of-the-valley and lemons. The cultivation of these fragrant orchids and their exalted elevation in art are symptomatic of the Chinese idea that fragrance is the heart of the flower. Indeed, Confucius referred to Oriental Cymbidiums as the “King of Fragrance” 「王者之香」, a phrase that is still in use today, having withstood the test of time and the rise and fall of dynasties.

The smell and flavour of natural vanilla created by adding or cooking the whole pods, powder or extract from orchids of the genus Vanilla are popular and ubiquitous in myriad foods and culinary dishes. There are at least 171 identified aromatic components in vanilla fruits. Even though no other orchid genus has achieved such global reputation with the odour of its fruit or flower comparable to that of the venerable Vanilla, there are indeed plenty of orchid genera, species and hybrids capable of filling rooms, houses and conservatories with odours containing rich combinations of volatile compounds when they are in flower. Nevertheless, it is still somewhat ironic that the widespread and long-lasting flowers of Phalaenopsis are largely odourless, whereas the specialist and short-lived blooms of Stanhopea are prodigiously fragrant. Hopefully, the renewed interest in breeding orchids specifically for their fragrance as well as the worldwide progress achieved in fragrance classification, competition and judging will result in more perfumed cultivars being available to orchid enthusiasts and the public in the future.

An interactive electronic form is available to anyone wishing to contribute one or more entries to the ✿❀ Scented Orchid Registration with Queensland Orchid International ❀✿, which is a database with two tables containing orchids listed alphabetically across two opposite categories: The Good Scent (Perfume and Fragrance) and The Bad Smell (Stink and Stench).

The Gallery on Page 2 of this post provides exemplary visual documentations of scented orchids. It is a permanent record of excellent or exceptional photos and videos uploaded to the Queensland Orchid International Facebook Group.

This special post features several friendly and witty discussions (entitled “Orchid Fragrances”, “Scent Descriptions” and “Smell like a Flower, Take a Shower”) on the wide-ranging Scents and Smells of orchids.

For those who are more technically minded, this post also outlines the science of scent production in orchids as well as the classification and judging of fragrances, plus some advice from orchidsamore and fragrance variation with orchids, followed by a list of relevant articles available online and a section on reference books.

Fragrant Orchids

Science of Scent Production

It is estimated that three quarters of orchids are scented. The scent of an orchid is produced in specialized glands called osmophores. Rich in stored lipids, the glands are characterized by intense physiological activity and biochemical turnover requiring high energy expenditure from the plant, even generating heat in some cases.

All parts of an orchid flower can produce odours, since osmophores can be located anywhere on a flower or bud, from petals and sepals to calluses and basal spurs, depending on function. On the one hand, osmophores may be diffusely located on an orchid flower to offer a general attraction to a pollinator. On the other hand, they can be confined to certain areas of the flower where a pollinator is enticed to remove or deposit pollinia in the process.

The scent of an orchid is most frequently produced on the lip, given that osmophores are most often situated at the hypochile, a rounded (globular), cupped (hood-shaped) or cylindrical structure connected to the rest of the flower and constituting the upper portion of the labellum.

Being volatile, the scented oils produced by orchid flowers can vaporize at specific temperatures, becoming available when pollinators are active. The scent can vary throughout the day both quantitatively and qualitatively as well as from day to day.

The scent release is quite an autonomous process, being strictly a light-controlled phenomenon regulated by a photochrome trigger within the flower. Hence, the inflorescence alone detects the presence or absence of daylight. Since the release is light-sensitive and independent of the orchid’s endogenous clock mechanism, it is also relatively independent of the orchid’s metabolism.

Let it be acknowledged here that the scent description of any orchid species is dependent on not just the subjectivity and variability of the human olfactory faculty as well as sociocultural factors pertaining to the perceiver, but also the variability of the scent resulting from cultural, environmental and/or clonal factors pertaining to the orchid species.

Furthermore, the absence of any floral odour on an orchid does not necessary indicate that the orchid is odourless, given that orchids have evolved with animals much longer than with humans, and that the human nose is limited in its range and sensitivity. In other words, our sense of smell is not specifically designed to detect the osmophores and nectaries present in the epidermis of the sepals and petals of many orchids. Craig Scott-Harden cited one example as follows:

Unfortunately when it comes to perfume, Pleurothallis marthae lies fair and square in the middle of the Hall of Mediocrity, having no definable odour! And yet I believe that this species attracts its pollinator by releasing a pheromone scent through osmophores located on the petals! Attracting night flying fungus gnats! So what may be indiscernible to us, has an almost hypnotic effect on the poor deceived gnat! So I wonder how the gnat would describe this perfume!

Those who are interested in learning more about Pleurothallis marthae may consult the scientific article entitled “Nocturnal pollination by fungus gnats of the colombian endemic species, Pleurothallis marthae”.

Married couple Simon and Emily of Inspiration Outdoors writing about Wildflowers of the Stirling Ranges: Best Wildflowers in Western Australia also have something witty to say about the “gnatty gritty” of scent lure as follows:

All’s fair in love and war

Honesty is not a desirable trait among many of our orchid friends and sexual deception of all kinds is rife among the 411 known species of Western Australian orchids. It’s not about push-up bras and horrible control briefs though – orchids have taken the seduction game to a whole new level. Here’s how our Bird Orchids (Pterostylis barbata and P.turfosa) do it…

Sex, lies and pheremones

Bird orchids attract their specific pollinator, a tiny gnat, by emitting a scent from a little pouch at the end of their labellum.… Some say it is the scent of the gnat’s favourite food – a delicious fungus which no gnat can resist. Others say the orchid releases a smell that is identical to the sex-attractant scent (or pheremone) that the female gnat releases, attracting virile young male gnats from far and wide.

Whether it’s sex or food that draws the gnat to the Bird Orchid, once it arrives there is little it can do to escape the clutches of the procreation-focused flower.

According to the interview entitled “Ep 6. Perfumery, persistence and parenthood with Anne Gaskett” published at in situ Science “showcasing the stories, discoveries and journeys of Australian scientists”:

Australia is what you call a hotspot for deception … these deceptive orchids are certainly much more common in Australia than other parts of the world. There’s [sic] 11 different genera, several hundred species, and it seems to be the result of six independent evolutions of sexual deception amongst the orchids in Australia, which is extraordinary because people often think of sexual deception as a crazy, quirky phenomenon. How on Earth did that happen? But it’s happened six times independently in Australia, and it’s also happened independently once or twice in Europe, but mostly in Central America and South America. But Australia’s certainly where it happened most.

Listen to the rest of the interview at podbean.com, stitcher.com, mytuner.mobi, player.fm or itunes.apple.com to find out why Australia is such a hotspot for mimicry and deception by scent and in other ways.

Specifically, the coevolution of insects (pollinators) and plants (orchids) as well as environmental variations and geographical differences can result in the divergent selection of flowering plants, leadng to phenotypic variations, which include the variation of floral scents. Entitled “Why Do Floral Perfumes Become Different? Region-Specific Selection on Floral Scent in a Terrestrial Orchid”, a 2016 research paper demonstrates that “[g]eographically structured phenotypic selection can lead to adaptive divergence” of an orchid:

In this study, we measured phenotypic selection on display size, floral color, and floral scent in four lowland and four mountain populations of the nectar-rewarding terrestrial orchid Gymnadenia odoratissima in two years. We also quantified population differences in these traits and pollinator community composition. Our results show positive selection on display size and positive, negative, or absence of selection on different scent compounds and floral color. Selection on the main scent compounds was consistently stronger in the lowlands than in the mountains, and lowland plants emitted higher amounts of most of these compounds. Pollinator community composition also differed between regions, suggesting different pollinators select for differences in floral volatiles. Overall, our study is the first to document consistent regional differences in selection on floral scent, suggesting this pattern of selection is one of the evolutionary forces contributing to regional divergence in floral chemical signaling.

N
O Oncidium crispum — musty, “like cockroaches”
P Pescatoria cerina — “quite strong, somewhat musty and extremely unpleasant, though not all of the other people who were asked to smell it agreed with this.

Pleurothallis cocornaensis — moldy socks
Phragmipedium caudatum — urine-like
Q
R
S Satyrium pumilum — “mimics the odor of decomposition, specifically that of a decaying mammalian carcass.”, “The stench was dominated by three chemical compounds. The first, 2-heptamone, is known for its banana-like fruity odor. The second, p-cresol, is a prominent component in human sweat. And the third, indole, produces an intense fecal odor. Mixed together, they generate the reek of decay. Moreover, these same three compounds dominate the scent of a rotting mammalian carcass, the favorite fare of flesh-fly larvae.”

Orchid Fragrances

Some of our orchids are beautiful, others interesting and then there are some that are hard to describe. Fragrance can be a consideration when it comes buying an orchid, It is for me. This subjective list of orchids and their fragrances might be of interest.

  • K-w SoundEagle Hi Jesus, according to my scent registry at https://queenslandorchid.wordpress.com/…/the-scents…/, Rhynchostylis coelestis smells like citrus, which is quite different to your scent description of “unperfumed soap”. I am intrigued and baffled. Could the scent of Rhynchostylis coelestis vary this much? What do you think, Michael? 13 August at 23:02 · Like · 1

  • Jesus M. Figueroa Vigo About the scent and smell, is there a more scientific way of determining what smell an orchid hace? It’s very subjective what I smell and associate the smell with is rather subjective, if I never smelled a citrus I would not describe a smell as citrious. Is there a more nuetral unsubjective way of describing scents and smell. 19 hrs · Unlike · 1

  • K-w SoundEagle Of course, it may not be entirely prudent for any of us to assume here that the scent variation of Rhynchostylis coelestis is entirely due to the subjectivity and variability of the human olfactory faculty, and not at all due to the variability of the scent of Rhynchostylis coelestis. Greg, would you have any experience on such matter? 18 hrs · Like · 1
  • K-w SoundEagle I have included the following paragraph at https://queenslandorchid.wordpress.com/…/the-scents…/: Let it be acknowledged here that the scent description of any orchid species is dependent on not just the subjectivity and variability of the human olfactory faculty as well as sociocultural factors pertaining to the perceiver, but also the variability of the scent resulting from cultural, environmental and/or clonal factors pertaining to the orchid species.

  • Craig Scott-Harden Ok time to shine! The first and most efficient thing one could do in determining different scents, even though most impractical would be the purchasing of a mass spectrometer??? This naturally would allow different scents and smells, to be broken down to there chemical elements! This can then be shown in graph form as a visual display! Now barring a win in Powerball this is highly unlikely in its viability! So how does one describe the stated example of citrus! The art of verbal artistry I think is called upon! My example for citrus (Orange) hence forth would be “A sweet slightly spicy, with floral undertones, pungent even pervasive in its intensity odour, depending on strength it can be slow to dissipate, prevailing in the back of the nostrils whilst others may fade quickly!” Now I am aware that this is subjective so I will finish off by simple saying, “That the nose knows? It is up to us as individuals, and using life’s experiences to bring forth images starting from a blank canvas to create a complete landscape formed by our senses ,our minds eye and our human ability to communicate such things! This is what defines us above other life! 13 hrs · Edited · Unlike · 2

Based on Linet Hamman’s talk given at the LOG seminar in November 1999
Published by the South African Orchid Society

There are certain (cor)relations between scents and floral colours:

  1. White floral image — a soft fragrance : The white-floral scents incorporate the very pleasing scent notes of jasmine, tuberose, orange flower, honeysuckle etc. These flowers really are white in the majority of cases and release their scent mainly during the late evening or night. Most are pollinated by moths which use the scent and white colouring as pointers to the flower.
  2. Rosy floral image — a sweet, rosy smell almost like Turkish Delight : The scent of cyclamen, lily of the valley, sweet pea and rose identify this group. Sunlight and warmth trigger scent production.
  3. Yellow scents — strong, citrus-like freesia fragrance
  4. Brown scents — reminding of spices; cloves, coriander; caraway and cinnamon : Typical scent of a carnation.
  5. Green scents — a mossy, wet / forest scent
  6. Dark smells — mostly unpleasant; musty, stale socks
  1. Intensity — the strength of fragrance
  2. Diffuseness — the degree to which one can smell it from a distance
  3. Pleasantness — how pleasant or unpleasant the fragrance is
  4. Elegance — how well-rounded and perfumistic the fragrance is; chemical notes or thin fragrances are detractions
  5. Instant appeal — whether one likes it and how much

If you desire fragrant orchids you should find them in bloom and smell them directly.

The [defunct] list given is too vague and will result in your buying plants that are a disappointment.

The [defunct] list included Brassia, of which I raise hundreds and have never had one with a scent I could detect. Admittedly my sense of smell is not great, but others may be the same. Nobile Dendrobium are listed but I again raise hundreds and would not sell them as a fragrant orchid.

A good example of fragrant orchids is the most famous Onc. Sharry Baby, the chocolate orchid. It normally it has a very strong Hershey bar chocolate scent. I have 100 in bloom and the fragrance is almost missing. You have to stick your face in the plant to smell it. Normally you would be hit with scent when you walk into the shadehouse. These are large plants that bloom twice a year and when they bloom again in the winter the same plants will have a very strong scent. The heat of the summer is reducing the scent.

Orchids put out scent to attract insets to pollinate themselves. If the weather is not right for the insects to be on the prowl (like damp rainy days, summer heat, winter cold, almost anything for at least one orchid) the orchid does not waste its perfume.

It is also not uncommon for an orchid to have no scent one year and then be very fragrant the next.

Young orchids blooming for the first or second time often have no scent on a plant that is famously fragrant.

Back to my original suggestion to find them in bloom and smell them. Then do not be disappointed the next year if it skips a year from having its environment changed.

Well every time I read information less clear I have which are the most fragrant, now I have lots of species supposedly very fragrant, however I propose to list with a ten, regardless of the moment they emit the fragrance in order to clarify a Little more still this subject since the bibliography is not conclusive from my point of view, greetings and until soon
