The best containers for forcing bulbs are azalea pots or bulb pans. (Azalea pots are '¾ the height, but with normal width' pots) However... you can use anything that you'd use for other houseplants as long as it drains well.
Buy a bulb pan or an azalea pot. Bulb pans are half as high as they are wide, and azalea pots are two-thirds as high as they are wide. They both have the most pleasing proportions for these little irises because a standard pot looks kind of massive.
