You could create an arrangement for any size vase, the larger the vase, the more flowers and greens to use. For Christmas time, use red, white and maybe even green flowers (like green button mums). Also choose from a variety of greens and evergreens out there. Accent a red rose in a bud vase with some baby's breath and cedar. Deep red alstroemeria are especially beautiful. There are many other flowers that would be perfect to use for Christmas arrangements, the link below will take you to a complete list of flowers, foliage, and evergreens for Christmas floral design.
Compact contemporary designs made to sit on coffee tables or shelving units arranged in deep colored stylish vases have maximum impact when packed with white roses and steel colors. Stunning bouquets comprising of clusters of the brightest yellow roses and separate clusters of fragrant blue hyacinths divided by folded banana leaves is exquisitely elegant.
