Brief description

Buddleja davidii Franch. is a shade-intolerant woody melliferous species. The deciduous shrub mostly thrives in various ruderal areas and disturbed grounds, which it colonises rapidly, but also grows in warm semi-natural habitats with well-drained soils like gravel shores, rock outcrops or open woodlands. Climate change is likely to trigger higher invasiveness in Europe during the next decades (Branquart et al. 2010). It often blooms as soon as it reaches a few tens of centimetres in height (Lambinon & Verloove 2012: 535).

Status and distribution in Luxembourg

In Luxembourg, Buddleja davidii was first documented in the wild by Gérard Schmidt on 5th August 1993 in the gravel quarries of Remerschen near Wintrange, Municipality of Schengen (Schmidt 1993; MNHNL 2000-). More than 100 observations of the butterfly-bush are documented in the data portal of the Museum (MNHNL, iNaturalist & GBIF 2019).

Summer lilac is widely cultivated in gardens across Luxembourg, from where it can easily make its way into the wild. The distribution map for Luxembourg shows that the species occurs most frequently in the south of the country, while no indications of Buddleja davidii “in the wild” exist for the Oesling.

A survey along the national railway network of Luxembourg revealed that summer lilac is spreading along the railway tracks in the South West of the country and in the Moselle valley (Pfeiffenschneider et al. 2014a).

Buddleja davidii has been spreading continuously in recent years, especially in urban environments, on rocks and railways (Krippel et al. 2018: 60-61).

The first observation of this species in its subspontaneous state in Belgium and northern France dates back to 1940. It spread mainly from the 1970s onwards (Lambinon & Verloove 2012: 535).

Risk assessment

ISEIA protocol: C2 (2+2+2+2) (Ries et al. 2013: 18).
