Any one out there know this plant?

I found it growing in one lake out in Citrus Park. I have never seen it in any other body of water in florida. It grows year around and blooms every day. I suspect somone dropped it into the lake years ago. It doesn't form a tuber like some lilies.

It roots along the shore, will grow in bog conditions, but also floats around in mats. The flowers shown in my picture are about 1/4 the size of the lake growing plants. The plant is not invasive and seems to fit in well with the natives. I am sure it is not native because there is another lake, seperated by a road and about 10 feet of dry land on either side of the road and it is not in the second lake (or any other lake nearby). It multiplies very well by offsets.

Any hints?
