Saguaros (Carnegiea gigantea) of (at least) three age groups. (Click on photo for a closer look and to see the smallest set.) They didn't get trampled, eaten, or burnt by the sun because the seeds fell (or were deposited) under the mesquite that acted as a nurse tree. The mesquite is on its way out - mesquites don't live nearly as long as saguaros - but it served as nurse for at least three generations. A very nice family portrait!
