Ornamental Grass + Seeds

As I was walking with some co-workers to Taco Bell for lunch, I saw an Ornamental Grass on the corner of Drumm and Washington in San Francisco with seeds ready to pop out. They were calling out, “Joey, take me… take me home!!!”… so I did. I’m not sure what variety it is, but I took a photo of the plant if anyone can figure out what it is. I’ll try to plant these in the spring and see what come out.
