 "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 double-flowered form is caused by a recessive gene variant (allele) in the homozygous condition.

 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. \\ 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.

 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. \\ The flower extract (n-hexan) consisted mainly of fatty acids (tetradecanoic acid 18%, hexadecanoic acid 12%) and alkanes (C14-C20).
