Status and distribution in Luxembourg

Records of Bidens frondosa L. in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2020-10-28.

Bidens frondosa L. was first documented in Luxembourg by Léopold Reichling and Marcel Etringer on 10th September 1959 on the bank of the Moselle between Stadtbredimus and Hüttermühle, 1 km downstream of the Paul Eyschen Monument, municipality of Stadtbredimus (Reichling 1962; Obs. key: DSS00465000000XF, MNHNL 2000-).

Currently, more than 70 observations of Bidens frondosa are documented, most of them originating in the Moselle valley (MNHNL, iNaturalist & GBIF 2019).

The species is currently expanding to the west of the flora territory (Lambinon & Verloove 2012: 722).
