Flowers are favorite party props for Southern hostesses, many of whom have gardens filled with white, which is useful when planning centerpieces. Other floral details can be created with what's on hand and in season. Here, we gathered tulips and mock orange from a spring garden. Fresh-cut daisies are an inexpensive treat from the florist. With loose, simple arranging, these flowers provide a perfect touch on the tables and chairs and even garnish some of the food. Old glass decanters and crystal bud vases make great centerpiece containers--a nice example of how to pair the old with the new.
