I am getting conflicting advise from 2 different florists. I am having a late September wedding and I want blue hydrangea for my bouquet. One florist (who is a friend of my SIL) says that they brown quickly and not to use them or go silk. A florist in my home town laughed and said that is ridiculous and said as long as I keep them in water until the ceremony and put them in water at the reception they will be fine. Does anyone have anyone have any experience with Hydrangea?
