Sorry, I'm originally from USDA 2a. In zones that cold, we dig up our tulips and jonquils and store them in the basement during the winter. Caladiums were store in the potato cupboard.rainbowgardener wrote:The caladiums are a nice suggestion. They are not winter hardy so they do have to be dug up in the fall and stored. I didn't quite follow the comparison with tulips and daffodils though. In most of the US tulips and daffs/ jonquils are winter hardy and are just left in the ground. In some of the warmest areas, Southern US, to have tulips you have to dig them up and refrigerate/ freeze them, because they need to have cold dormancy. That is still different from caladium which are stored warm.
