There are six categories of bearded iris based on the plants height which may range from 8-36 in. tall. Iris can be grown easily in soil with good drainage to which compost has been added. Do not use animal manure, high nitrogen fertilizers nor mulches in iris beds as they can encourage rhizome rot. Grow in full sun to light shade, water 1-2 times a week in summer, but keep rhizomes dry during dormancy from November through March. This plant is not bothered by rabbits, squirrels nor deer.
