Brief description

Aster lanceolatus Willd. thrives both in ruderal and riparian areas, especially on rich and moist to humid soils. Commonly planted in gardens, it then gets propagated through fly-tipping of green waste. Seed development depends on climatic conditions. Asters are rhizomatous species, and can propagate clonally. They easily form dense and wide monospecific colonies, displacing native wetland plants, and favouring the sedimentation and stabilization of riverbanks, which reduces the ability of rivers to meander and flood (Branquart et al. 2010).

Status and distribution in Luxembourg

In Luxembourg, Aster lanceolatus Willd. was first collected by Jos Witry on 24th August 1934 in Grevenmacher (Specimen № 52294, MNHNL 2000-b). It is not specified if it was cultivated or not.

The species was first recorded in the wild by François Léon Lefort (1917-1975) on 30 September 1949 by the river Sûre in Diekirch (Obs. key: DSS0043900000VKC, MNHNL 2000-b).

Currently, 15 records of the species are accessible through the MNHNL-mdata portal, most of them in the Moselle valley (MNHNL, iNaturalist & GBIF 2019).

According to Lambinon & Verloove (2012: 706), the species occurs as quite common to quite rare (AC-AR) around villages, vacant lots, wastelands, and river banks, as subspontaneous or naturalised.

Other Aster taxa

  1. Aster dumosus L. (Syn.: Symphyotrichum dumosum (L.) G. L. Nesom): the bushy aster is first reported by Tinant on the banks of the Moselle (Wirtgen 1842: 89; Lefort 1950: 41). A hybrid Aster dumosus x novi-belgii was collected by Paul Grzonka and Léopold Reichling on 29 September 1959 in Bech-Kleinmacher in the Moselle valley (MNHNL 2000-b).
  2. Aster novi-belgii L.: confused Michaelmas-daisy, first mentioned in 1872 in the wild in Luxembourg.
  3. Aster ×salignus: this hybrid between A. lanceolatus x A. novi-belgii is much confused with both its parents, particularly A. lanceolatus. The common michaelmas daisy was first mentioned by Yves Krippel in 2001 at Pällembierg (MNHNL 2000-b).
