Tucson's landscape

Those who haven't been to the Arizona desert might imagine it to be barren. It is anything but. Not only are there 2600 varieties of cactus in the area surrounding Tucson, but there are many trees as well. Green Valley is a city south of Tucson, and one might think that an odd name for a city in the desert. However, when one looks over this area from above, it is green, thanks to trees which hang onto their leaves throughout the winter and to the ubiquitous Palo Verde tree, which has a rich green bark which carries on photosynthesis even after the tree loses its leaves.
