About Plumeria Fragrances

The Plumeria smells is unique, like no other flower. Each cultivar has its own unique fragrance. The flowers are often very fragrant, the palette of their smells covers lots of nuances: soft, fruity, peachy, and creamy. Some plumerias smell sweet or spicy, others smell like jasmine, peaches or citrus. Some of the strongest scents include honeysuckle, gardenia, lemon other scents are grape, coconut, rose, ginger and many more.

In the proof-reading phases of the University of Hawaii’s Plumeria Cultivars in Hawaii bulletin 158, the editor disagreed with the authors on the nature of the fragrance of several of the plumeria cultivars. It brought to mind the differences that people come with in describing odors. Plumeria flower fragrances can be described as weak, mild or strong, with the strongly scented ones characterized in terms of other fragrances: citrus, coconut, rose, cinnamon, carnation, jasmine, gardenia, fruity, or even woody.

  • Fragrance: This is a very subjective measurement. Most plumeria enthusiasts know what a plumeria smells like. It smells like a plumeria! What a surprise! The scent is wonderful, but indescribable. Sometimes we call it floral sweet and other times we describe it as simply plumeria. When another description can be applied, in our opinion, we use it.
  • Intensity of Fragrance: Another subjective measurement, made within the context of plumeria. We rated each variety on a zero to three scale. Zero was used when we could detect no fragrance, one for a light to mild fragrance, two for moderate to strong, and three for heavy.


‘Common Yellow’

In ‘Common Yellow’ 73 different compounds were identified by comparing their mass spectra and GC (gas chromatography) retention times with those of reference chemicals, while 67 were identified in ‘Irma Bryan’. It is possible that differences such as thes e could be used sometime to help distinguish between other cultivars which are closer in appearance.

‘Common Yellow’ has as major components the compounds phenylacetaldehyde and linalol (16.1 and 14.1 percent, respectively). Also present are:

  • trans, trans farnesol (11.0%),
  • beta phenylethyl alcohol (8.8%),
  • geraniol (5.4%), and
  • alpha-terpineol (2.8%).

Two other compounds, neral and geranial, with lemon-like fragrances were present (comprising together 0.9%) which help account for the characteristic citrus scent of this flower.

 ‘Irma Bryan’

‘Irma Bryan’ had a very different makeup, although phenylacetaldehyde (12.1%) was still present. Beta-phenylethyl alcohol comprised 31.6% of the essential oil, about 3 times as much as in ‘Common Yellow.’ It has a mild, warm, rose-honey-like odor. The phe nylacetaldehyde has a powerful and penetrating, pungent-green, floral and sweet hyacinth-type odor.

Other volatiles that were present in the ‘Common Yellow’ flowers were either absent or present at much lower levels in ‘Irma Bryan,’ while methyl cinnamate (1.0%) and 2-methylbutan-1-o1 (10.5%) were found in the red ‘Irma Bryan’ flowers and not in the ‘Co mmon Yellow.’ Methyl cinnamate has a powerful fruity-spicy odor and seems to characterize ‘Irma Bryan’ while the 2-methylbutan-1-o1 does not seem to contribute to its scent.

Does it make the wonderful plumeria fragrance the less exquisite to know that 12 hydrocarbons, 21 alcohols, 13 esters, 8 aldehydes, and 20 miscellaneous compounds were detected?

So, when asked what creates the wonderful plumeria scent, you can reply authoritatively and quote the chemical names. On the other hand, you can paraphrase Joyce Kilmer and state that only God can make a plumeria.


In the summer of 1991, Japanese researchers collected plumeria flowers in Hawaii to analyze them. The cultivars chosen were the ‘Common Yellow’ and ‘Irma Bryan’ forms of Plumeria rubra L.

Nearly a pound of flowers of each cultivar were subjected to steam distillation and extraction with organic solvents to derive a mere 70 milligrams (0.002 oz) of essential oil. Gas chromatography and mass spectrometry analyses were carried out to characterize the various volatile components.
