Whenever I travel to other areas of the United States, I enjoy the different flowers and trees. Crepe Myrtle is common in the South but non-existent here in Arizona. I am sure the heat and lack of humidity are a factor, but you would think that it would grow in some areas of the state. I think that growing flowers is a good indicator of the level of civilization found in any area of the country. A land without flowers, is a land without education and culture.
