Brief description

Slipbladige rudbeckia 20-08-2005 18.25.12Rudbeckia laciniata L. mostly grows in open ruderal and alluvial habitats (e.g. river banks). Seeds may only germinate from bare soil; the low germination and recruitment rates in undisturbed sites reduce plant capacity to colonise natural plant communities. The plant can however form dense and monospecific stands due to vegetative growth (rhizomes). R. laciniata, or coneflower, locally decreases plant species richness and hinders colonisation of open habitats by tree species, especially in riparian areas. The plant is toxic for livestock but also very melliferous (Branquart et al. 2010).

Status and distribution in Luxembourg

Records of Rudbeckia laciniata L. in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2024-03-27.

Rudbeckia laciniata L. was first mentioned for Luxembourg in the wild in the surroundings of Mersch by Feltgen (1901: 254).

The oldest herbarium specimen of Rudbeckia laciniata L. at the MNHNL was collected on 20 August 1935 by Jos. Witry in gardens in Schifflange (Specimen № 50794, MNHNL 2000-). The next scientific record that we know of was made by Léopold Reichling (1921-2009) on 12th June 1961 near the river Alzette in the municipality of Walferdange (MNHNL 2000-).

Currently, 2 records of coneflower are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2019).

This melliferous species from North America is naturalised in Europe, especially in central Europe. River and canal banks, river gravel, sometimes wasteland. Sometimes subspontaneous or adventitious. Sometimes cultivated for garden ornament (Lambinon & Verloove 2012: 719).

The species is comparable to Helianthus tuberosus in its ecology but is much less common in Luxembourg.
