Brief description

Solidago gigantea L. can grow in a wide range of soil conditions but is not shade-tolerant. The plant is found in many disturbed and nitrogen-rich sites such as ruderal areas, fallow lands, abandoned fields, river banks, etc. and also colonises humid grasslands. It can build up dense and long-lasting populations and easily outcompete native plants, including tree seedlings. Competitive ability is favoured by allelopathic interactions. Once established, the plant may remain dominant for a long period of time and often prevents natural colonisation by woody species (Branquart et al. 2010).

Status and distribution in Luxembourg

The oldest herbarium specimen at the MNHNL was collected under its synonym Solidago serotina Aiton on 8 September 1887 by Jean Feltgen (1833-1904) in a garden (“jardin Bosseler”) in Mersch (Specimen № 15601, MNHNL 2000-). The next record is a herbarium specimen collected by Jos Witry on 15 July 1937 in gardens in Rumelange (Specimen № 50850, MNHNL 2000-).

The first documented record in the wild was reported on 22 September 1960 by Léopold Reichling (1921-2009) in several locations of the Grund district in Luxembourg City (Bock, Stierchen, Breedewee) (MNHNL 2000-).

Currently, 78 records of tall goldenrod are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2019).

This melliferous species native to North America is naturalised in Europe: fairly common to fairly rare, present in waterfronts, forest edges, wastelands, wastelands; often in large stands (Lambinon & Verloove 2012: 703).

This species includes populations in North America with variable chromosome numbers. Naturalised plants in Europe have generally been reported to Solidago gigantea subsp. serotina (O. Kuntze) McNeill, still known to be tetraploid. The question remains, however, whether Solidago gigantea subsp. gigantea, diploid, also exists in Europe, and especially whether the two taxa are morphologically identifiable. The problem remains to be studied in the wild (Lambinon & Verloove 2012: 703).
