Answer:
Iris is a genus of rhizomatous plants in the Iridaceae family.
Step-by-step explanation:
Members of this genus are perennial herbaceous plants that grow from creeping rhizomes (rhizomatous irises) or, in drier climates, from bulbs (bulbous irises). They have long and erect flower stems, which can be simple or branched, solid or hollow and flattened or with circular cross sections.
