Roses (Rosa spp.) in old cemeteries in the Wielkopolska region (W Poland)

This paper presents all taxa of the genus Rosa recorded in 2005–2015 in old cemeteries in Wielkopolska. In the past, roses were frequently planted in cemeteries as ornamentals, contributing to their beauty and specific atmosphere, but they also had many symbolic meanings. Today, historical roses are rare. As a result of floristic research in 2,169 old, neglected cemeteries in Wielkopolska, 35 taxa of roses were found. These include 21 alien taxa and 6 taxa new to Poland.
