Iris florentina is the white-flowered to pale lavender variant of Iris germanica. Collected in Italy, and then introduced to Northern Europe in about 1500. It is cultivated as an ornamental plant in temperate regions worldwide, and grown to produce orris root – a scented substance used in perfumes, soaps, tooth cleanser, and laundry powder. Medicinally it was used as an expectorant and decongestant.
