Hydrangea is my favorite flower, followed by calla lily, tulip, lisianthus, anemone and rose (except red and white roses). The two flowers to avoid in wedding (for Chinese) are chrysanthemum and gladioly, typically used to honor the dead.
I have determined to use blue hydrangea in my bouquet, probably along with calla lily and some other flowers. The florist told me hydrangea is a "thirsty" flower, it requires water consistently to keep its beauty. Anyhow, I don't think this is a big issue, as long as I keep the bouquet in a vase at all times except when I'm walking down the aisle.
The three bridal bouquets below look absolutely gorgeous, but I must make some alterations if they are mine, either add more colors or take the white flowers out. It seems blue hydrangea is commonly placed with white flowers. I think blue and white look lovely together, it's unfortunate that I can't use this combination.

Other pretty bouquet arrangements of blue hydrangea with roses.
I like hand tied style bouquet the most, ideally wrapped with ribbon with some pins or crystals. The two designs below look very elegant and stylish.
