Talk to your florist about the color and style of your wedding. Give them an indication about what will work for you. By doing this, you will allow the florist to have a great idea or two about your wedding flowers so that they can ultimately provide you with something that works perfectly.
For some, it is not about which flowers they wan tin their wedding, but rather which flowers they do not want! If there are flowers that you do not like and don't want to see in the finished product, tell the florist about this when ordering flowers.
