Florists like to cover their "mechanics" (green floral foam) in clear containers. This can be done in a variety of ways, including marbles, fruit slices, and wrapping in large leaves such as Aspidistra or Ti Leaves. Fresh greenery below the water line, however, can contribute to bacteria buildup in the water. Wrapping in a waterproof ribbon that mimics the look of fresh leaves is the answer!
They make beautiful accents to party favors, centerpieces, table setting and even bouquets.
