Okay, first keep in mine I am DIYing my flowers, and ordering them from Sam's Club, so I'm keeping it pretty simple. Also, my wedding colors are green & white.
For bouquets, I was going to get white hydrangeas and carnations. My bouquet would be only white hydrangeas; the bridesmaid bouquets would be white hydrangeas and the carnations, but I will "dye" them green with food coloring (I'd rather do this myself than order green carnations, so I can control the shade of green they are).
For my centerpieces I am having different sizes/shapes of milk glass vases, 3-4 per table, with a stem of light pink spray roses in each vase, and more of the green carnations. (Most of my vases are bud vases and can't fit more than 1 stem, which is why I like the spray roses since there's a few buds on each stem, even though they're smaller).
What do you think? I'm not a big flower person, so it's hard for me to find ones I like. Plus, our reception is mostly outdoors, in Spring, with tons of flowering bushes and trees, so I don't want my centerpieces to try and compete with that.
