Can you plant the large white calla lily underwater in a pond?

Hi--

I have a large white calla lily planted on the dry bank of my pond and it has just flowered and looks like it is dying. Most of the leaves have died and the ones left are very pale. The plant became pale on transplanting it, perhaps too much hot sun . Can it be planted like my other water lilies under 4 or 5 inches of water in my pond? I live in the deep south and have a half acre pond. Is the dying out part of the flowering cycle? Should it be planted in shade or partial shade since I'm in the south or will the pond suffice?

It is also called, Common Calla and it does grow up to 2 to 4 ft high. My book, Sunset Western Garden book said that this Calla thrives in moist, even boggy, soil all year. Originally from South Africa, but it doesn't like too much hot sun. I would say if you plant it in the light shade and wet area, it'll do better. It worth a try?
Reply:Cosmos has it. Yes, they do grow tall. No, they should not be planted under water. Use It as a damp ground marginal plant.
Reply:I agree with Gidget. It probably isn't a calla lily. They only thrive in full sun, and I've never seen one 4' tall. No, nothing, except aquatic plants survive under water.
Reply:i think what you have is a peace lily yes it can be used as a aquatic plant just make sure you anchor it well diffused light is always best for any plant
