„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.“ https://en.wikipedia.org/wiki/Sweet_pea

„The major components of the scent of cut sweet pea flowers (Lathyrus odoratus L. cv Royal Wedding) are (E) and (Z)-ocimene, linalool, nerol, geraniol and phenylacetaldehyde. The aroma is almost exclusively produced by the standard and wing petals, with very little emanating from the keel petals and other floral structures.“ The mean percentage contribution of the five major components of the aroma of fully opened sweet peas are (E)-ocimene 2.3%, (Z)-ocimene 41.5%, linalool 29.8%, nerol 10.5%, geraniol 8.5% and phenylacetaldehyde 6.4%.
