Yes. You must be careful not to damage the roots, however.
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.
Iris flowers and leaves are used for flower arrangements. Iris roots are sometimes used to flavor liquors. In general, iris parts are mildly toxic.
Irises have either bulbs or rhizomes.
If you don't want the iris, dig them up. They have very shallow roots so it won't be hard.
Plants with fibrous roots can be transplnted very easl; with proper care all plants can be transplanted.
Don't eat iris. It has a irritating resinous compound that is mostly concentrated in the root but the leaves also have it.
Some irises are moved in spring and others in fall.
This is common when a tree is transplanted on a hot day and/or the roots are disturbed too much while transplanting, or it was not watered in well. It's best to transplant in fall or early spring when a tree is dormant and without leaves so not dependent upon the roots to supply water to leaves.

Yes they can be transplanted.
Plug plants are young plants, usually seedlings, grown in individual cells of compost enabling them to be pricked out or transplanted without disturbing the roots.
