This is jointhead grass. Here is a helpful webpage about life cycle and control: http://www.na.fs.fed.us/fhp/invasive_plants/weeds/jointhead-grass.pdf

This page from Virginia Tech provides great photos: http://oak.ppws.vt.edu/~flessner/weedguide/arahi.htm

Unfortunately, this weed is becoming more common and is very hard to control.
