Iris germanica aka German Iris

Iris germanica, also known as the bearded iris or German bearded iris, is a rhizomatous perennial that blooms in mid to late spring. It can grow up to 120 cm tall and 30 cm wide, with roots that can reach up to 10 cm deep. This species belongs to a group of hybrids and includes varieties such as I. × g. var. florentina. With hundreds of hybrids available, this plant comes in almost every color except bright scarlet. In addition to its ornamental value, the plant also has medicinal uses. The rare houseplant known as Orris-root is a type of Iris germanica that is relatively easy to grow, provided it receives regular watering and is placed in direct light within a foot of a window.
