The rose was named the official flower and floral emblem of the United States in 1986. Roses have existed for 35 million years and grow naturally throughout North America. Roses can be red, pink, white, or yellow, and most have a pleasant aroma. Rose hips, which is the fruit of the flower which grows from the bloom of the flower, is a common ingredient in herbal teas. The petals are also edible and are sometimes used to garnish desserts or sprinkled in salads and provide a distinctive flavor. Since ancient times, rose hips and petals have been ingredients in medicines. The rose is also the state flower of five states, including New York, Oklahoma (Oklahoma rose), Georgia (Cherokee rose), and Iowa and North Dakota (wild prairie rose).
