Roses, chrysanthemums, statice and carnations are available all winter long because they're grown in places with warm climates, such as Africa and South America, and imported to the United States.
Place flowers immediately in fresh water when you get them home. Remove the leaves from the lower portions of the stem. Inspect the flowers and remove any wilted or damaged petals. Cut 1 inch off the stems and place the flowers in ice water for at least an hour before arranging.
Some flowers such as narcissus and amaryllis are available during the holiday season because they bloom in white and red. Other flowers, such as poinsettias, are offered as potted plants and as cut flowers in floral arrangements.
