Ken,
I generally grow them in pots, but just at the surface, like an iris. I partially bury the pots to make them more aesthetically pleasing, same as my plumeria. the ones that are still "working" in late October get put on the kitchen cabinets, where the skylight/sun windows allow 4-7 hours of sun a day for them.
I already dig callas, cannas, elephant ears, calladiums and a variety of other things, potted is easier.
