A bouquet of yellow roses now brings to mind all of the sunny, cheerful feelings of warmth and happiness. In contrast to the romantic meanings attributed to other roses, the yellow rose is purely a symbol for friendship. This gives it a unique place in the pantheon of roses. Yellow roses can send the perfect message of appreciation and platonic love without the romantic subtext of other colors. They can represent feelings of joy and delight, and are an ideal way to brighten someone's day who may be feeling down. There is perhaps no other flower that is able to bring out a smile in quite the way that a yellow rose can. (ProFlowers.com)
