Green foxtail is a bright green clumping annual weed common in turf and pasture areas. The seedheads can be distinguished from those of other foxtails because they are smaller and greener with long hairs. Yellow foxtail has a wider seedhead, with shorter bristles. In addition, yellow foxtail has hairs on the leaf margins and ligule. Giant foxtail has the largest seedhead of the three and this seedhead is drooping.
