Mixing pink and red roses together in one bouquet communicates both appreciation and love. The respective meanings of the pink and red roses are synthesized into a single expression. In a bouquet, this combination is perhaps more significant than a bundle of exclusively pink or exclusively red roses; it communicates the positive and touching sentiments of both colors:I appreciate you and I love you. A bouquet of both pink and red roses is an ideal gift on Valentine's Day, because it demonstrates not only passion but gratitude. For the same reason, it is an appropriate bouquet to celebrate significant anniversaries in a marriage or other love relationship.
