An interesting fact about roses is that scientists found a rose fossil that is approximately 35 million years old in Colorado. Another fact is that the Rosa genus includes over 150 species that grow in nature all around the Northern Hemisphere, including Holland, Mexico and North Africa. Something that very few people know is that black roses are not black, as most people think. They are very dark red.
A fascinating fact about roses is that over half of the surface of the ground in Ecuador has roses growing on it. In addition, over 80 percent of land in Zambia serves primarily for rose cultivation. The reason for such a phenomenon is that the rose industry provides a large source of income for the population of those countries.
Another interesting fact about roses is that the color of roses conveys a particular emotion. For example, pink roses are a sign of romance and gentleness; red roses show passion, love and deep feelings, and yellow roses mean empathy, happiness and familiar love.
The rose has been the official National Floral Emblem of the United States since Oct. 7, 1986. Roses are also the state flowers of Georgia, Iowa, New York, North Dakota and the District of Columbia.
