In 1988 a new cultivar of park rose was described as Rosa ‘Poznań’, however, the above name was used in 1966 for a large-flowered garden rose, which probably disappeared from cultivation. Several years ago the new name Rosa ‘Poznańska’ was proposed in the electronic trade catalogue to replace the later homonymous epithet, but it was at variance with the rules of International Code of Nomenclature for Cultivated Plants (Article 25). The cultivar name Rosa ‘Poznańska’ is thus published here for the first time. Rosa ‘Poznańska’ is a large shrub with erect main stems covered with thin needle-like prickles in the lower part only, usually ± hairy in places; its leaves are large, green, wrinkled, glabrous, with broad stipules; flowers are large, pink, simple, sepals entire, bracts broadly ovate, receptacle and pedicels smooth; fruits usually undeveloped (Figs 1–4). It is probably a segregate of a hybrid of Rosa rugosa Thunb. with R. blanda Aiton, very hardy and disease resistant.
