After irises have finished flowering, you should cut back the flower stalks to the base of the plant. Remove any dead or yellowing leaves and continue to water the plant regularly. Fertilize the irises with a balanced fertilizer to promote healthy growth. It is also important to divide overcrowded clumps of irises every few years to ensure optimal blooming.

Dutch iris and all irises are perennials.
Most irises have rhizomes but some have bulbs.
Yes, apart from garden varieties, there are wild irises.
No, you cannot regrow irises from a cut flower. Irises propagate through their rhizomes, which are underground stems, rather than from cut flowers. To grow new irises, you need to divide the rhizomes of existing plants or plant iris bulbs. Cut flowers do not have the necessary structures to produce new plants.

I would use "irises."
It's best to plant irises in the spring, but they can be transplanted in the fall. The rhizome (brown part with roots on it) should not be completely covered or the irises will not bloom. They like plenty of sunshine and shouldn't be in a place that doesn't drain well or the rhizomes will rot.
