Some type of Calla?

Bought these tubers sold as "Calla Lilies" several years ago.but they don't look like any of my other Callas.I've never seen them bloom but they come back every year (surrounded by foliage of Verbena 'Homestead Purple' here). I think I am going to pull these , several of the Cannas and the elephant ears and start a tropicalesque garden somewhere. Perhaps, I could save some caladium bulbs too. Castor bean plants would fit well into that scheme too, alongwith New Guinea impatiens. Maybe a mini container water garden as well? Or, a little bog? I've also been wanting to get some clumping bamboos.That gives me something fun to think about , cool! Now to find the space for all this.
