“…str., has been reported from several countries in Europe, including Austria, Italy, the United Kingdom, Germany, Denmark, Sweden, Norway, Poland, Lithuania, Latvia, and Russia (Pliszko 2015;Gudžin-skas and Petrulaitis 2016;Pagitz 2016;Pliszko and Zalewska-Gałosz 2016). It occurs in some of the typical sites in which S. canadensis is found as naturalized or invasive, including abandoned fields, roadsides, railway embankments, ruderal ground, disused quarries, and tree plantations (Nilsson 1976;Burton 1980;Sunding 1989;Pliszko 2013;Stace et al 2015;Pliszko and Zając 2016). It was also reported from arable field within a grass-legume mixture (Pliszko and Jaźwa 2017).…”

“…Recent data from Austria and Lithuania indicate that S. 9 niederederi forms locally established populations, associated with the parental species (Pagitz and Lechner-Pagitz 2015;Gudžinskas and Ž alneravičius 2016;Pagitz 2016). In Poland, S. 9 niederederi is known from several dozen localities (Pliszko and Zając 2016) and its naturalization is under consideration. It has been observed since 2011 in Mieruniszki, north-eastern Poland (Pliszko 2013), where it first started growing probably in 2009, which suggests that it can easily survive in the wild during a few seasons or even longer.…”

In this study, the authors aimed to revise the ability of Solidago 9 niederederi, a hybrid between S. canadensis and S. virgaurea, to produce sexual ramets and seedlings as a part of its naturalization strategy. Based on a two-season garden cultivation experiment, we showed that the hybrid produces more generative ramets than vegetative ones and the number of generative ramets increases from one season to another with an increasing number of stem buds located on the caudices. We also revealed a spontaneous seedling recruitment by the hybrid during cultivation in the garden. Based on the seed germination test under laboratory conditions, we evidenced that the hybrid can reach a higher final germination percentage than S. canadensis but a lower one than S. virgaurea. Based on field studies conducted in 35 populations in Poland, the hybrid formed the largest populations in tree plantations and on abandoned fields, reaching 16.5 and 15.7 ramet clusters on average, respectively. The most abundant populations were found on abandoned fields; however, the mean number of ramets per cluster did not differ remarkably among habitats (H = 6.5, p = 0.163). In all populations, the mean number of vegetative ramets per cluster reached 0.85, while the generative ones achieved 6.43 on average. The statistical analysis proved that the aforementioned differences are significant (t = -12.6, p = 0.0002). Our results suggest that S. 9 niederederi is able to generate its own offspring by sexual reproduction and that abandoned fields seem to be the most suitable habitats for its establishment.

“…Solidago ×niederederi Khek, a natural hybrid between the North American S. canadensis L. and the European S. virgaurea (Pliszko 2015;Karpavičienė and Radušienė 2016;Pliszko and Zalewska-Gałosz 2016;Radušienė et al 2018), occurs in several countries in Europe and is treated as an alien taxon (Pliszko and Kostrakiewicz-Gierałt 2017b;Jaźwa et al 2018). It occupies anthropogenic habitats such as abandoned fields, roadsides, railway embankments, disused quarries, tree plantations, forest clearings, and tracks, usually together with its parental species (Nilsson 1976;Burton 1980;Sunding 1989;Stace et al 2015;Gudžinskas and Petrulaitis 2016;Pliszko and Kostrakiewicz-Gierałt 2017b;Pliszko et al 2017. Similarly to S. canadensis and S. virgaurea, the hybrid is a perennial plant and spreads by wind-dispersed fruits (cypselae) (Pliszko andKostrakiewicz-Gierałt 2017b, 2019).…”

In Solidago, the pappus, a modified calyx, protects ovary and fruit from predation and is strongly involved in anemochory. In this study, we aimed to test the hypothesis that the mechanical removal of pappus decreases the final percentage and speed of seed germination. We examined S. ×niederederi, a natural hybrid between invasive S. canadensis and native S. virgaurea, in comparison to its parental species and S. gigantea. We conducted a 21-day germination test in the laboratory, using 50 fruits with intact pappus and 50 fruits with removed pappus in four replicates, for each taxon. The statistical analysis demonstrated that the final percentage of germinated seeds was remarkably lower in the group of fruits with removed pappus in S. canadensis (p ≤ 0.05) and S. gigantea (p ≤ 0.05). Moreover, the speed of seed germination was also significantly lower after pappus removal in S. canadensis and S. gigantea, based on the Timson's index (p ≤ 0.05). In the case of S. ×niederederi and S. virgaurea, the hypothesis was rejected. We assumed that the small size of the cypselae could be responsible for the negative effect of pappus removal on seed germination.

“…Populations of the hybrid S. × niederederi Khek, 1905, whose parent species are S. canadensis and S. virgaurea Linnaeus, 1753, are widespread in Europe. It is widespread in Austria, Great Britain, Lithuania, and Poland (Pagitz, 2016), and in recent decades, the expansion of its range has continued intensively (Karpavičiené and Radušiené, 2016;Pliszko and Zajac, 2016). Since most records of S. × niederederi are from Northeastern Europe, we also decided to conduct research in this region.…”

Two invasive species of goldenrod of North American origin, Solidago canadensis and S. gigantea, widely spread in Europe, are known to be able to form hybrids with the native goldenrod S. virgaurea. In the Kaliningrad Region of Russia and in Lithuania, we found plants morphologically classified as the hybrids S. × snarskisii (= S. gigantea × S. virgaurea) and S. × niederederi (= S. canadensis × S. virgaurea). Analysis of the nuclear ribosomal internal transcribed spacer 1–2 (ITS 1–2) showed the ambiguity of the origin of the alleged hybrids. Thus, in S. × niederederi, the nucleotide substitutions that differentiate the parent species S. virgaurea and S. canadensis had ambiguous readings, indicating heterozygosity, which confirmed the hybridogenic origin of the individuals. However, for many specimens of S. × snarskisii, the hybridogenic origin was not confirmed. Occasionally, hybrids do occur, but appear to be soon absorbed by the maternal species. An analysis of the chloroplast non-coding intergenic spacer rpl32–trnL showed that in these rare cases, the maternal species is S. virgaurea, and the paternal one is S. gigantea.
