„… but it is extensively cultivated as an ornamental plant…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 scent of the flowers is composed mainly of trans-β-ocimene, followed by phenylacetaldehyde and 2-phenylethanol.

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 important components were linalool, lilac aldyhdes A, lilac aldehyde B, 2-phenyl acetonitrile, nonanal and decanal.
