Ben and I have been photographing jacarandas. We can't help it.
I found this tree at 300 W. Green Street, just south of the Ralph's parking lot. Well, I didn't find the tree. If you're anywhere in the vicinity of this block of Green you can't miss it. The building behind it is marked "Hall of Administration." It could either be administration for the Ambassador Auditorium or for Marantha High School, both of which are south of (behind) this structure. Ambassador kind of matches it, though.
But back to the tree. Have you downloaded Google Earth? Oh, you should. It's a fun program anyway. I learned my way around Paris with it before I even went there. You can explore the world, or just Pasadena. Check out your house, the mountain trails, or the great aerial view of City Hall. And if you type in the address above (300 W. Green St. Pasadena, CA), you'll see the most prominent feature at that address: the huge, purple jacaranda tree, photographed by satellite.
