The Oklahoma rose was designated the official state flower of Oklahoma in 2004. One of the most fragrant of hybrid tea roses, the Oklahoma rose is dark red, nearly black velvet in warm weather. Long pointed buds open into huge, fully double blooms that are extremely fragrant with wonderfully strong, sweet old rose perfume.

The rose has been around for about 35 million years and grows naturally throughout North America. The rose is our national flower, and several states have adopted roses as official state symbols: the rose in New York, Cherokee rose in Georgia, and the wild prairie rose in Iowa and North Dakota.

Rose 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).
