 "Sweet peas have been cultivated since the 17th century and a vast number of cultivars are commercially available. They are grown for their flower colour (usually in pastel shades of blue, pink, purple and white, including bi-colours), and for their intense unique fragrance."

 +The scent of sweet pea flowers may be characterised as '//rosy-floral'// based on such compounds like citronellol, nerol, geraniol, citral, and rose oxide. Special notes are added by phenylacetaldehyde, phenylacetaldoxime, esters of phenylacetic acid, methyl anthranilate, and indol. \\

 +Main volatile components of the floral fragrances from three sweet pea cultivars were (E)-β-ocimene (22.9-46.5%) with (Z)-β-ocimene (2.3-7.3%), linalool (16.6-23.6%), nerol (3.3-10.1%), geraniol (4.5-6.5%), phenylacetaldehyde (2.9-6.5%), and (E)-α-bergamotene (1.3-6.8%). Minor constituents were e.g. 3-methylbutanal, esters like methyl butanoate and methyl hexanoate, α-pinene, benzaldehyde, rose oxide, benzyl alcohol, methyl benzoate, citronellal, decanal, β-citronellol, citral, neryl acetate, geranyl acetate, β-caryophyllene, and benzyl 3-methylbutanoate. \\
