Gabriel,
When ordering TB/IB rhizomes I prefer to plant in Mar-Apr to give a good start over the summer. But potted ones that are well rooted could be put into the ground as Bonnie mentioned. You have a few more weeks until heavy freeze, so should have enough time for the roots to acclimate to the new locations. They should all bloom next spring if you keep the soil around them during transplant.
Post pictures next Apr-Jun!
