Yellow foxtail and giant foxtail

Here two kinds of foxtail grow along a paved trail in Prophetstown State Park. The kind with the yellow seedhead that stands straight up is yellow foxtail (Setaria lutescens) The kind that is greener and has the bigger droopy seedhead is giant foxtail (Setaria faberi).

Big bluestem (Andropogon gerardii) has been established in this restored prairie and this prairie grass and the other prairie plants are dominant except where the park mows a strip of land alongside the pavement. The continual mowing creates a new habitat where annual plants like foxtails and Queen Anne's Lace will invade and outcompete the prairie vegetation. Pictures taken at Prophetstown State Park, August 9, 2009.
