For bridesmaids, consider bouquets of hydrangea. This big flower will pack a lot of "OOMF" with just a few stems. You can opt for white like the ones here, or add a little color! Personally, I like the idea of going with all white for the bridesmaids and then adding a little bit of color to the bridal bouquet. Creates a beautiful pop against a white gown!
White Wedding Flowers: This grand centerpiece is a definite crowd pleaser, the tall vase is filled with crystals and accented by crystal strands dripping from an arrangement of roses, hydrangeas and orchids.
