Sometimes great trees are found in strange places. Carrotwood (Cupaniopsis anacardioides) is an Australian tree in the soapberry family. It don't seem to do well in San Francisco - you rarely see one that looks healthy. So it's always a pleasure to walk past this thriving tree, in the 100 block of Sacramento Street. Who would have thought that the best example of a tree would be in a cement planter in the middle of the financial district?
