Single, larger blossom flowers, such as roses, carnations, zinnias, tulips or lilies, usually make up the focal points of a piece. Taller stems with multiple flowers can balance things nicely. Delphinium, gladiolus, and snapdragon are good examples of flowers that can add extra height and texture. "Filler" flowers, or stems with many small buds, are great for topping of a bouquet with a full and delicate look.
A Christmas centerpiece can be made in several ways. You can either create a simple centerpiece of an arrangement of flowers in a low crystal container or make a long centerpiece in a plastic centerpiece tray with a variety of evergreens. Written instructions and step by step videos for how to assemble a Christmas centerpiece using a centerpiece tray and evergreens can be found at my website, along with a list of materials and resources where materials can be acquired. You can also look at our blog to see pictures of a beautiful arrangement of flowers in a holiday crystal container.
