I would read up on how to do it, then see if you can’t experiment with some silk flowers to figure it out! I think it’s going to depend on the flower type.

i found this:

If you chose to do your own centerpieces, here are some tips from No Fuss Fabulous:1. In order for your flowers not to float to the top of your vase, you will need to a) attach the stems to the bottom of the vase with aquarium glue or b) use fishing weights. Fishing weights are small silver weights sold at hardware stores. Attach weights onto the flower with clear fishing wire and let it sink – cover up with decorative stones or c) for some flowers simply adding decorative stones or pebbles to the bottom of each vase around stems keep the flowers from floating to the top.

2. If you use regular tap water, bubbles may eventually begin to form on your flowers. Use distilled water to prevent bubbling.3. Real flowers are recommended. If you use silk flowers, make sure you test them in water to prevent bleeding. I have heard that synthetic flowers work better than silk.4. If your arrangement starts to look too heavy, try submerging only half of your flowers. I have been to a few events where they only submerged a portion of the flowers and they looked quite lovely. See photo below offlowers not fully submerged.5. In water, everything is magnified. A floating wire or fraying silk flower will show. Be sure that your pieces are well put together before adding water.6. Depending on the flower you choose, the blooms can look nice up to a week submerged in water. The length of time your centerpiece will look fresh depends not only on the flower you choose, but also how much jostling will take place. This is something to think about if you are hauling a few of them to a wedding reception or other event.

We had the water submerged centerpieces and went throught the same decision process you did.  Utimately we liked the look of real live flowers but wanted to be able to get them done ahead of time esp since our venue wanted us to get insurance if we were to do any centerpiece assembly on site.  We were going to use silk flowers until i came upon these real touch flowers that seriously look and feel like the real thing!  Jackpot!  They look so much like real live flowers under water, our guests couldn’t tell the difference and they were able to take them home as a keepsake as well.  (There are many different types of real touch flowers – some of which look and feel plasticy). 

After a few trial runs, and settling on a design – we set a production line and completed them weeks in advance of our big day.  That was one big check off the to do list!  The assembled vase contained a layer of river rocks, the orchids strung with transparent fish wire and anchored with a river rock so they dont float to the top, and a floating candle. We packed them up and delivered to the venue.

They were super easy to take care of on the wedding day.  The venue took care of placing the vases on the tables,  pouring water to about 1.5 inches from the top of the vase and lighting the candle a few mins prior to our reception start time.

The number of blooms you need depends on the size of the vase and how full of a look you want.  We used 3 orchids per vase for a full look.  We did have to experiment with the floating candles. the first pack of floaters i purchased stated a 4 hour burn time but they fizzled after about 1 hour.  So i recomended testing your candles to make sure they will hold up to your entire event duration.

Feel free to PM me if you have any other questions and good luck!

I did this kind of centerpeice for a graduation dinner last June and used bouganvillea for the flowers. Bouganvillea require almost no arranging and went with the less is more approach. We used several different colors (one per centerpiece) including a peachy orange and the nature of these blooms made the colors POP when lit underneath while submerged. I left a few green leaves for a nice touch. I did have trouble with them floating but now I realize what I need to do next time with the anchoring. The best part of this though — I took cuttings from around the neighborhood and did three centerpieces each for 40 tables and paid ZERO dollars for the flowers.
