You can probably envision what you want your wedding to look like. The hard part is getting that image across to the florist. Even the most conservative list of standard wedding flowers runs into the hundreds of varieties, so what are you going to do when you need to find that special orchid hybrid you vaguely remember liking 15 years ago?
Start keeping notes early. Clip magazine photographs, collect files from online wedding Web sites, and plunder Facebook profiles and Flickr accounts of friends and strangers alike for wedding pictures. The more information you can give your florist, the better. The research will refine your choices, making it easier for your florist to provide a perfect realization of your vision.
