Stage a summer celebration of fruit and flowers as a spectacular centerpiece. Floating orchards of brightly colored citrus candles bob gently atop leafy sprays of viburnum in hand-blown, scissor-cut glass cylinders or bowls. Fill a companion cylinder with golden, ever-ripe lemons on their stems or an assortment of colorful shells and sand. For the perfect backdrop, roll out a brightly stitched saffron orange table runner of gauzy double-ply cotton.
