A compact forsythia reaching 2 m, with fresh yellow flowers; sold in Europe by 2003 (Hatch 2021–2022) and probably of Polish origin. Its parentage is given as F. × intermedia ‘Vitellina’ × F. ovata (Arbofux 2021), the same as ‘Fontanna’. Like ‘Fontanna’ it is sometimes treated as a cultivar of F. viridissima (Hatch 2021–2022).
