yellow foxtail, Setaria pumila

Yellow? In a later season this will turn yellow. The seed heads with all their spikes become very attractive, waving around in the autumn sun. This one got a head start on looking good, taking root in this old rail tie. Yellow foxtail is an almost universal companion, growing in all states and provinces except AK, LB, NT, NU, and YT, and it is on SPM. Lenawee Co MI, 9/7/12. Grass family, Poaceae.
