Maybe a pot of dry sand...
I'd want to plant them out in the garden as soon as I could!
KentPfeiffer said: Do you know what kind of iris they are?
If they are bearded irises, they won't be happy in that bucket for long and they probably won't do well if planted into a wet environment. On the other hand, if they are Japanese irises or Iris pseudacorus. you will want to keep them in that bucket until they can be planted and they should do fine if planted in or near a pond.
Either way, cutting the leaves back a bit would be beneficial.
For what it's worth, they look like bearded iris rhizomes to me, but that's no guarantee that they are.
