Importance and distribution in Luxembourg
Steeple-bush is a shrub tolerant to permanently water-logged soils and fluctuating water tables. It occurs mainly in riparian habitats such as swamps, marshes and bogs. This pioneer species needs full sunlight for optimal growth, flowering and fruiting but may survive under the tree canopy. Contrary to other North American Spiraea species, steeple-bush may produce fertile seeds under Central European climatic conditions. The species can easily form dense monospecific thickets that can colonise large areas, displace other plant species and generally dominate communities in wetland areas. It can rapidly colonise clearcut areas (Source: http://ias.biodiversity.be/species/show/139).
The first documented occurrence of the species in Luxembourg dates from 1959. It was found by J. Wirty on 20th June 1959 in Greiveldange, municipality of Stadtbredimus (Herbier specimen). In the Recorder database, no observations of the species are documented though.
