Taro is fairly easy to store in a pot of dirt, I would have thought, that can dry out and cope with frost free storage as a tuber.... or you could bring it in and grow it as a potted houseplant

Umbrella palm does not make a tuber to speak of, it does have resilient roots which don't tolerate drying out. Umbrella palm grows real easy in water alone if you perk it with a change of water now and then. A handfull of dirt would be adequate to supply some fertility. All you need to bring in are several well rooted sprigs, just watch them go, go, go...

Both are tolerant of poor light levels, though don't be surprised if umbrella palm grows to massive proportions when it has settled indoors... it grows very, very big in shady conditions...
