A Polish hybrid probably deriving from Bolesław Suszka’s breeding work in the 1950s; it is listed as F. × intermedia ‘Vitellina’ × F. ovata (Arbofux 2021) but is also described by Arboretum Wirty in Poland as a hybrid of F. × intermedia with F. koreana. It was introduced to the Chicago Botanic Garden in the United States by Kris Jarantoski in 2000 (Chicago Botanic Garden 2020).
‘Maluch’ – the name means ‘little child’ in Polish – is very hardy and forms a compact, regularly-branchy bush only 1 m high; its abundant flowers are golden yellow with much darker markings in the throat (Chicago Botanic Garden 2020). Its narrow, grey-green leaves are sometimes trifoliate.
