On the buffet table three heights of cylinder vases will have green bear grass inside the vase twisting up the vase and three pomander balls on top of green hydrangeas and white anemones with looped green bear grass in between them sporadically. Also three skinny cylinders surrounding with floating candles and bands of black and white stripped ribbon.
I'm thinking one head of blue hydrangeas each for the bridesmaids, plus a lot of greens - so more greens than hydrangeas (since their dresses are already blue).
One Flower Extravaganza - Hydrangeas bloom profusely in summer, making them a good choice for an at-home wedding. This centerpiece sas created in an interesting urn.
