This is some kind of Coral Tree, but I don't know what kind it is.  Balboa Park is a national treasure in a country of civic parks... and one of the reasons Balboa Park is very special is the climate.  Here in this region almost any living plant can thrive.  Redwood trees have a hard time because there is so little water, but the dying Redwoods in Balboa Park are dying for lack of adequate water.  It's not the fault of the tree that it is dying.  Whether we want to find a way to provide the kind of water needed for Redwoods to survive and thrive is a matter of choice for voters.  Perhaps we should not try to grow every kind of tree here.  Perhaps trees that require great amounts of water should be available to us through books and not by actually planting the trees.  Apparently the Coral Trees, there are several in the Park, can thrive here because they get the right amount of water and sunshine and everything else they need.  I took the pictures for today's blog on my way back to the car in a parking area between the Natural History Museum and the Zoo.  If you know the exact name of this plant, let me know. All of the pictures today were taken at the same tree.
