Erect deciduous shrub, stems many, with almost straight prickles and more abundant acicles; leaves with 2-3 pairs of leaflets, leaflets broadly elliptic, glabrous and usually deep green and slightly shining above, margins 1-2-serrate, with glandular hairs; flowers clustered 1-3, fragrant, petals 20-30mm long, broadly obovate, rose, crimson or purplish rose.

„Little is known about the further history of the rose after the fall of the Roman Empire. Around 800 AD, in the Capitulare de villis of Charlemagne, roses are recommended for cultivation. At that time, roses were used as medicinal plants. In particular, the petals of the apothecary rose (R. gallica 'Officinalis') were used against diarrhea, as a gargle and as baths for poorly healing wounds.“

The pale pink flowers of the famous old French rose, R.gallica hybrid 'Duchesse de Montebello' (Laffay, France, 1829) give off a fresh-floral rosy scent of the May rose type. Main components of the headspace are phenylethanol (30.4%), phenylethyl acetate (6.9%), citronellol (6.0%), nerol (3.8%), myrcene (7.6%), α-pinene (5.8%), and β-caryophyllene (4.2%).

Main components of the headspace of Rosa gallica flowers collected on Tenax were alcohols like phenylethanol (41.8%) and nerol (2.6%), esters like geranyl acetate (18.1%) and phenylethyl acetate (7.7%), and sesquiterpenes like germacrene D (4.4%), and bourbobene (2.1%).

Pentane/dichloromethane extracts of Rosa gallica petals showed phenylethanol as the main component (highest content of all old roses, up to 89.9%), followed by hydrocarbons (up to 28.5%). Other components were benzyl alcohol (0.2-10.6%), nerol (0-18.6%), geraniol (0.1-30.6%), geranyl acetate (0-4.4%), benzyl benzoat (0.1-1.0%) and nonanal/cis-rose oxide (0-0.2%). 4-Vinylphenol (0.2-10.6%) was detected in two samples of Rosa gallica.
