The rose was designated official state flower of New York in 1955. The rose has been around for about 35 million years and grows naturally throughout North America. The petals and rose hips are edible and have been used in medicines since ancient times.

Rose hips (the fruit of the rose which forms at base of the flower) are a nutritional treasure chest - rich in vitamins (C, E, and K), pectin, beta-carotene, and bio-flavinoids. These elements produce a strong antioxidant effect which protects and enhances the immune system. Rose hips improve blood cholesterol and pressure, digestive efficiency, and weight management (and are also a special winter treat for birds and wild animals).

Roses are red, pink, white, or yellow and can have a wonderfully rich aroma. The rose is a symbol of love and beauty (as well as war and politics) the world over. The rose is also our national flower, the state flower of Georgis is the Cherokee rose, and the wild prairie rose is state flower of Iowa and North Dakota). See all 50 states.
