Importance and distribution in Luxembourg
In Luxembourg, the plant was first documented in the wild in 1961. There is only a single record of Rudbeckia laciniata in the Recorder data base: It was found by Léopold Reichling on 12th June 1961 near the river Alzette in the municipality of Walferdange. The species is comparable to Helianthus tuberosus in its ecology but is much less common in Luxembourg.
The plant mostly grows in open ruderal and alluvial habitats (e.g. riverbanks). 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 (Source: http://ias.biodiversity.be/species/show/93).
