The best advice to remember is to keep the order as general and open as possible.  Because flowers are usually better in some seasons and not others, it is wise to allow the florist to pick the types of flowers used so they can give you the best quality.  Some flowers, such as roses, carnations and chrysanthemums, are available all year.

In addition, not all colors are available for all types of flowers.  While you can specify the overall color or colors of the arrangement (e.g., spring colors, fall colors, pastels, etc.), it again is wise to allow the florist to pick the individual colors and flowers so they can give you the best quality.
