Galanthus woronowii cultivation, it has frequently been confused with two other species, "Galanthus platyphyllus" (usually under its synonym "G. latifolius") and "Galanthus ikariae". All three species have broad green leaves arranged in a supervolute pattern (i.e. wrapped round one another at the base), and inner tepals with a green mark only at the apex. The inner tepals of "G. platyphyllus" lack a sinus at the apex, i.e. they do not have a notched edge. "G. ikariae" and "G. woronowii" are similar, although molecular studies have shown that they are distinct species. Some differences are: Galanthus woronowii Galanthus woronowii, the green snowdrop or
