The identity of the plant first described by Carl Linnaeus as Iris florentina remains unclear, as of December 2021. In horticulture, it has been treated as a white-flowered variant of Iris × germanica, under names such as Iris germanica nothovar. florentina, Iris × germanica var. florentina and Iris × germanica 'Florentina'. Iris florentina has also been treated as the correct name for the true species also known as Iris albicans Lange.

Iris × germanica is the accepted name for a species of flowering plants in the family Iridaceae commonly known as the bearded iris or the German bearded iris. It is one of a group of hybrid origin. Varieties include I. × g. var. florentina.
