You can add light and color to a pond with floating decorations. Floating candles in wax luminaries deliver a gentle glow. Floating fresh flower balls and wreaths can dress up a pond for a special occasion like a party or a backyard wedding. The luminaries can be left in natural white, or tinted to match flower shades for a coordinated color theme. Flowers with large and sturdy blooms, like chrysanthemums, daisies or roses, make long-lasting fresh flower balls and wreaths.
