Brief description

Rosa rugosa Thunb. is a predominantly coastal shrub species, which grows on dunes, in grasslands and healthlands but also in coastal woodlands. However, it can grow further inland, where it can be found in fields, boreal forest, disturbed areas, grasslands, heathlands, riparian zones, temperate broadleaf forest and in urban areas. Open dry grasslands, as well as heathlands, especially those with bare patches, are potentially in danger of an invasion by R. rugosa. The species also occurs in various open ruderal habitats like road verges, railway embankments or waste ground (garden escape), but appears to grow less vigorously there.

Rosa rugosa forms extensive impenetrable thickets due to root and stem suckering. It displaces the natural flora of beach and dune vegetation and outcompetes early successional plant species in these habitats (Arenaria serpyllifolia, Empetrum nigrum, Festuca rubra, Veronica arvensis, Viola tricolor, etc.). Thickets of R. rugosa are species-poor, irrespective of the dune type on which the shrub has established. They change humus conditions, favour the installation of other neophytes like Lupinus polyphyllus and Parthenocissus inserta and alter habitat structure through shading effect and initiation of dune formation. They may also act as a reservoir for potential pest species like gall-forming insects. Hybrids with native Rosa species occur (Branquart et al. 2010).

Status and distribution in Luxembourg

Rosa rugosa Thunb. is commonly planted in public green areas and private gardens in Luxembourg since a long time, as documented in old newspapers (Anonym 1923): “Large-fruited rosehips Rosa rugosa and Rosa villosa are popular rosehip varieties for conserving.”² We thus consider the first record of Rosa rugosa as cultivated species to be anterior to 1923.

Rosa rugosa Thunb. was first documented in the wild by Guy Colling on 15th June 2002 in the Stréissel nature reserve, north of the municipality of Bettembourg (MNHNL 2000-).

Currently, 15 records of Japanese rose are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2019).

The east Asian melliferous species is often cultivated for ornamental purposes in parks and along roadsides. Subspontaneous or naturalised: coastal dunes, roadsides, embankments, stream banks, especially in the west (Lambinon & Verloove 2012: 362).
