„The flowers, 1.5–2.5cm in diameter, often fragrant, are white, pink, red, or purple, and borne in summer through fall (autumn). The flowers are grouped in panicles, hence the specific epithet paniculata.“

The fragrant volatiles of Phlox paniculata hybrids were collected by dynamic and vacuum headspace analysis. The products of the vacuum process contained mainly 2-pheyl ethanol (12-17%) and linalool (3-9%). Cinnamic alcohol was found only in the vaccum product, together with 3-hydroxy-1-phenyl-2-butanone (1-4%), 3-hydroxy-4-phenyl-2-butanone (3-7%) and 1-phenyl-2,3-butanediol (0.3-6%). Phenylacetaldehyde (1-2%), benzaldehyde (0.3-5%) and benzyl alcohol (0.2-2%) were found in the dynamic headspace and in the vaccum headspace products. lilac alcohols, eugenol methyl ether, isoeugenol methyl ether and germacrene-D are additional main volatiles of Phlox flowers.

Scent emission analysis of P.paniculata flowers showed the benzenoids benzaldehyde (14-91 ng/hr/flower), 2-phenylacetaldehyde (14-61 ng/hr/flower) and methyl eugenol (11-47 ng/hr/flower) as main constituents, together with (E)-β-ocimene (13-28 ng/hr/flower). Other components were linalool, lilac aldehyde A, lilac aldehyde B, 2-phenyl acetonitrile, eugenol and methyl isoeugenol as well as nonanal and decanal.
