General note on Parthenocissus spp.

Originally observed in man-made habitats, these popular garden plants can be found increasingly in natural habitats like coastal dunes, riparian habitats and wood margins (Parthenocissus inserta) or rock outcrops (Parthenocissus quinquefolia). They usually thrive on nutrient-rich soils. Seeds are dispersed over long distances by birds. With its dense growth, the plant may cover, out-compete and kill native vegetation (Branquart et al. 2011).

Status and distribution in Luxembourg

Parthenocissus quinquefolia (L.) Planch. was first documented by Léopold Reichling (1921-2009) on 1 June 1958 at the Stromberg peak in the municipality of Schengen (MNHNL 2000-).

Currently, 12 records of the five-leaved Virginia creeper are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2019).

Parthenocissus inserta (A. Kerner) Fritsch has long been confused with Parthenocissus quinquefolia (L.) Planch. originating from North America. However, the latter is distinguished by its more branched twists (5-8 twists per twist, compared to gen. 3-5 in P. inserta), with branches provided at their end with a differentiated adhesive disc (simply swollen at their end in P. inserta) and by its leaflets with more obtuse and generally less deep teeth. A hybrid between the two species is also reported. It remains to be seen whether P. quinquefolia and the above-mentioned hybrid have been found in a subspontaneous state in the wild (Lambinon & Verloove 2012: 457).

Example of escape into the wild

The five-leaved Virginia creeper escaped from Camping du moulin in Bivels into the neighbouring ruderal and alluvial vegetation along the barrage lake of the river Our. The plants overgrow the vegetation on the ground and the shrub layer, and climb to the top of ash and alder trees. Photos: C. Ries, 29 April 2020.
