W artykule przedstawiono rozmieszczenie w Polsce róży labradorskiej Rosa blanda Ait. na podstawie danych z literatury, dostępnych materiałów zielnikowych, a także udostępnionych danych niepublikowanych. R. blanda jest gatunkiem północnoamerykańskim, który jest uprawiany i zdziczał na terytorium całej Polski, gdzie posiada status zadomowionego, nieinwazyjnego kenofita. Gatunek ten jest rzadki w Polsce. Zidentyfikowano tylko 22 stanowiska (głównie w środkowej i północno-zachodniej części kraju), powstałe prawdopodobnie spontanicznie lub będące pozostałością starych, lokalnych upraw. Nie można jednak wykluczyć w przyszłości zachowania inwazyjnego i negatywnego wpływu na rodzime gatunki flory, zwłaszcza że gatunek ten ma tendencję do krzyżowania się z innymi gatunkami (w tym inwazyjną R. rugosa Thunb.).

The article presents the Smooth rose, Rosa blanda Ait. distribution in Poland based on literature data, available herbarium materials, and shared unpublished data. R. blanda is a North American species that is cultivated and has become wild throughout Poland, where it has the status of a domestic, non-invasive kenophyte. This species is rare in Poland. Only 22 sites have been identified (mainly in the central and northwestern part of the country), as created spontaneously or as remaining from old, local cultivations. However, it cannot be excluded that this species will become invasive in the future and will negatively affect native flora species, especially through its ability to cross with other rose species (including invasive R. rugosa Thunb.).

Synanthropisation of vegetation is today a serious problem both due to its impact on plant and animal diversity, as well as its significance through the impact on the global and local economy in the direct and indirect direction. Understanding the mechanisms of new arrivals is one of the important aspects of many types of research. The presented paper concerns the analysis of selected features of kenophytes occurring on the Proszowice Plateau (Southern Poland). On the basis of long-term floristic studies, a list of kenophytes was selected. The list was subject to a detailed analysis of the frequency, origin, ecological numbers, life forms, and life strategies. The results indicate that perennial species with a CR life strategy have the greatest chance of expansion in the agricultural area, although the annual species with the C strategy predominate.
