Pretty Weeds

As I was taking a break at work. I noticed this this spent Dandelion flower under a tree on the sidewalk (The Embarcadero/Levi’s Plaza Park, San Francisco). Luckily, I was carrying my camera and I snapped up this photo:

I then noticed more weeds.

Anyone know what these two weeds are?

Right before writing this entry, I responded to comment about one of my older Oxalis photos. I then remembered that I had another photo of light purple Oxalis that grow as weed in our cactus and succulent pots. I just leave them and enjoy there added color.
