Ligularia Cass.

Ligularia is a Eurasian genus with ca. 125-140 species (Mabberley 2008, Liu & Illarionova 2011). Only two species are native in Europe (Chater 1976) while its highest diversity obviously lies in eastern temperate Asia with 123 species in China (of which 89 endemic) (Liu & Illarionova 2011). Out of these several are cultivated as garden ornamentals (e.g. Dress 1962, Schmid 1989, Springate 2000, Jäger & al. 2008), the least rare probably being Ligularia dentata (A. Gray) H. Hara. This species has also naturalized locally outside of its native distribution area, for instance in North America (Barkley 2006) and has been recorded as an escape or more or less established throw-out in Belgium as well. The identification of plants in cultivation is often complicated, partly as a result of hybridization. Some are probably best referred to as ‘groups’ or ‘aggregates’, for instance the Ligularia sibirica group or L. fischeri group (Springate 2000).
