Does anyone know what this weed is?

As I was walking to the carpool from work (San Francisco), I saw this weed growing through the grill underneath a street tree. I thought is was cool, so I took a few cutting of it to try to root.

Unknown Weed

The stems are reddish brown and slightly hairy. The main stem seems semi-woody, since I could not pinch it off. Anyone know what this is?

Here is a close up of the leaves.

Added May 16: I went back to check to see if this "weed" was really a sucker from the tree it was under. After seeing it, I don't think it is, since I also another of this "weed" at another location that was not under a tree.

Here are more photo's that may help:
