The best birthday flowers suggestion for your girlfriend or wife is always red roses. Although red roses symbolize love and romance and are always an appropriate choice for your wife they might not be the right choice for your girlfriend if a relationship is new. In this case, pink or any other colored roses would be an appropriate choice as well as any favorite flower your girlfriend has mentioned.
Different months of the year have corresponding flowers, much like birthstones. January is the snowdrop and carnation; February the primrose and violet; March the violet and jonquil; April flowers are the daisy and sweet pea; May represents lily of the valley and hawthorn; June is the rose and honeysuckle; July the water lily and larkspur; August represents the gladiolus and poppy; September the Morning Glory and Aster; October the Marigold; November, chrysanthemum; and December birthday’s the Poinsettia and Holly.
Regardless of whose birthday it is whether man or woman, son or daughter, husband or wife, girlfriend or boyfriend, flowers are always an appropriate and thoughtful gift that will be appreciated immensely.
