Yup, Jonna, that's the true 'Aquatic Banana' which is it's Common Name. (another very misleading Common Name)
Craig grows it from seed and posted pix of it at Koiphen.
In my opinion as a professional landscape designer, unless you have a HUGE pond, like the ones Jonna posted, it looks silly to grow a huge plant in a little pond. Not only that, big plants create big shade which will not help your lilies bloom. In my landscape designs, I plant large leafy plants on the edge of the pond which gives you the large focal point without making your pond look smaller and crowded/cluttered/busy.
Jonna's pond looks great with the cannas and large plants planted in the background and around the edges.
Gives the lilies plenty of room to grow and plenty of sun.
Of course if you have a veggie filter, any big plant would look great in it as a focal point.
