"starlord" expounded:

The best thing she can do is to put them in Pots for the winter, this should
keep them alive and growing. Then once they are ready to be planted put them
in a new bed. This is IF they are the Tall Beaded Iris, if they are L.A.
Iris then they should be taken inside and placed in something like a bucket
of water and placed where they get a bit of light from a window.

Being zone 6 I would think they are TBI's, in that case as said above, pot
them up and place them outside then.

I seriously doubt they'll make it if they're just potted up, they'll
freeze solidly, thaw, etc. over and over and rot by the spring. Much
better off to put them in the ground somewhere, not where they'll
ultimately be, even in a shady corner, and then properly plant them in
the spring.
