The reception site is not the only background that is important for your florist to take into account. She also needs to know what your gown looks like so she can design an appropriate bouquet for you to carry. Since you should have your gown picked out at this point, you should be able to show your florist what it looks like, such as is it white or cream, is it classic or modern, or how ornate it is, so she can make a bouquet that matches the dress and highlights it without detracting from its assets.

Since your bouquet is a part of the larger theme of the floral arrangements, it is important to show her the style of your dress immediately so she can coordinate the rest of the wedding into what will look best with your dress. Your dress is the centerpiece of your wedding day and the rest of your wedding is coordinated around the style and type of dress you have, so showing your florist the dress will allow her to have a clearer idea about your wedding style and themes.
