Coordinate colors with the natural decor of the room: wallpaper and table linens.In spring and summer, add bright colors found in seasonal flowers such as hydrangeas, roses, peonies, tulips, and orchids.
Make smart combinations: like red with sunset colors, blue with green, yellow, and pastels. Or keep it simple and go monochromatic.
Variety is important: be sure to use three and four different colors.
Expert Tip: Consider the final height of your centerpiece. Choose taller flowers like peonies for a buffet, or shorter flowers like daffodils or hyacinths in a dining room.
