So my solution is to either use artifical flowers, or not use flowers at all.
At the moment, I'm leaning towards non floral centrepieces. My first thought is Candles:
I absolutely love the look of candle centrepieces. They are so simple, but the effect is very elegant. My only fear is that it would still be daylight during our meal, so it might look a bit odd to have a table full of candles and no need for them to be lit...
Also, I think i'd like a bit more colour in our centrepieces. Of course, we could always use coloured candles - I love this picture:
