Flowers & Decorations Clashing?

I am planning my wedding for August 28, 2010. My fiance and I have decided on red & white for our wedding colors. Of course, black is involved also due to the suits. I want a white dress, with a red ribbon around the waist, my bridesmaids in red, tea-length dresses & the groomsmen in white shirts, red vests/ties & black suits. My question is if I like the idea of red gerber daisies for the flowers but like the idea of white candles on the table with maybe a single red daisy in the center, if its going to seem clashy between romantic [candles] and summery [daisies] ??
