Last week when we visited the Glendale Xeriscape Garden, I took this picture of a giant saguaro surrounded by a yucca (left), ocotillo (right) with an evergreen elm tree in the background. All of these are examples of low-water consumption vegetation.
The holes in the saguaro are usually burrowed out by flickers or woodpeckers but can be occupied by cactus wrens, elf owls and a variety of other desert birds. We really are enjoying learning about our desert environment. Click on the image to enlarge.
