Flowers I can submerge for centerpieces

I'm getting married on a lake, so I'm trying to stick with the whole water theme. I am renting 20" square vases and getting river rock to go in the bottom. I like the idea of completely submerging flowers in water to the top. So far I have experimented with a Phalaenopsis orchid, and it looks beautiful. However they are $5-10 each and I'm wondering if there are cheaper alternatives!
Anyone know of good flowers that could be submerged, that come in white? I'm getting married in July and thought about tulips, but they won't be blooming anymore

We had a row of submerged calla lilies topped with a floating candle for the escort card table.  While our callas were yellow, callas do come in white.  

Aha...found Picture.

Dogwood branches (if still in season in your area) is another possibility.

you can use silk Phalaenopsis orchids and they look amazing... try it ... no one will know they're not fresh flowers.

So silk flowers work okay? I thought I'd heard something about them not working as well for submerged centerpieces...
