Importance and distribution in Luxembourg

Distribution map of Aster novi-belgii L. in Luxembourg. Recorder-LUX & iNaturalist, 2019.08.26.

The first documented occurrence of the species in Luxembourg dates from 1951. It was found on 16th September 1951 in the Municipality of Rosport (Beck et al. 1952). Only five observations are indicated in the Recorder database (08/01/2018).

The confused Michaelmas-daisy is a flowering herb that thrives mostly in ruderal and waste areas, especially those with rich and moist soils. Initial dispersal occurs mostly by means of fly-tipping. Once established in an area, the plant spreads vegetatively – seeds do not seem able to mature under Belgian climatic conditions. The same should be true for Luxembourg.

Risk assessment

ISEIA protocol: C1 (1+1+1+1) (Ries et al. 2013: 18).
