„The double-flowered form is caused by a recessive gene variant (allele) in the homozygous condition. Therefore,… heterozygous single-flowered stocks should produce one quarter doubles in their offspring… Selection over the centuries has greatly improved these ratios, resulting in the so-called „ever-sporting“ stock… In these varieties, the singleness allele is closely linked to a pollen-lethal gene… many modern strains produce doubles in even higher proportions: 60% or even 80%.“

The flowers emit a pleasant floral, clove-like odor which is attributed to constituents like 2-phenylethanol, anol (4-propenylphenol), eugenol, methyl eugenol, isoeugenol, and related compounds. Vaccum headspace concentrates contain nitriles and isothiocyanates as artifacts.

From the volatile compounds isolated from M.incana flower oil (SDE), the main ones were β-pinene(13.2%), 3-carene(10.1%),(-)-isoledene(4.8%), β-bourbonene (4.5%), spathulenol (3.3%) and β-cadinene(3.2%).

The flower extract (n-hexan) consisted mainly of fatty acids (tetradecanoic acid 18%, hexadecanoic acid 12%) and alkanes (C14-C20). Monoterpenes detected were limonene, α-terpineol, geraniol, sabinene, and myrcene.
